There is a book covering backups that is supposed to be the Bible for backups.  Unfortunately, I am not where I can lay hands on it and can't remember the title.

If you can give us some more details about what you are looking for
(number of boxes, backup device you want to use, whether you want
simple backup or archiving, etc), you can probably get some better
answers.

My personal favorite for my desktop and laptop is using 'dar' with big
USB hard drives....but that's what works well for me.

I use rdiff-backup, which is ideal for backing up automatically to a
hard drive. I run it from cron, hourly on critical directories, daily on
the rest. I then have a weekly cron script that compresses the backup
directories with squashfs and writes them to ISO images ready for writing
to bootable DVDs. It makes restoring individual files very easy, and a
completely hosed system can be fixed because the DVDs are bootable.

Thanks all for the answers until now;

What i am looking for is to backup 3 servers, and a critical issue workstation.

I have a storage working with samba, so my bakups will go to this
samba server. I would like to make some diff bakups to save storage
space ....

:)

thanks again all of you....

got interested on backups on large USB disks too ...

A fair point, although it does make keeping spare, off-site backups
rather expensive :(

rdiff-backup should be excellent with a USB hard disk, I may give it a go.

Do you back up hidden files and directories in the home directory?
There seems to be a lot of junk in there.  Does something like
'--exclude "/home/user/.*"' work with tar?

I pretty much back up everything that's not ubiquitous on the Internet
on a on an external drive. Disk space is so cheap these days so I figure
why not.

yes, they contain settings, pw, all the juicy stuff. I tar everything onto 
tape.

Yes you may exclude files from being included. From the tar man page:

--exclude PATTERN	exclude files based upon PATTERN

-X, --exclude-from FILE	exclude files listed in FILE

In a Gentoo system nothing is really standard, so I backup everything
from / and then have a small exclude list with things like:

/dev, /proc, /sys, /exports, /var/cache/squid, /srv/BackupPC.


/var contains the most important files on a Gentoo system, if you loss
the portage installed software information your in a heap of trouble.
Goes both ways though backup of portages var information is less useful
without backup of everything installed.


I'm undecided about /usr/portage, I could save some time backing up
/usr/portage/distfiles, but it is easily generated content.



Minimal backup - if your willing to spend the hours on getting thing
back up and running.

/etc /root /home /usr/local /var

It's possible to make an exclude list for /var as it contains both
variable data thats important to save and dynamic data that will be
generated again.

A lot of things you're asking for can be accomplished with a script I've
used (and successfully recovered with) called a stage 4 backup [1].  It's
just your standard bash script that uses tar, gzip, bzip2, etc. to create
manageable backups.  I have my server set to backup once a month (I don't
make significant changes to it very often).

I'd like to know which parts from /var are actually needed. Do we need 
anything more than /var/mail, /var/lib/portage/world and /var/log?

/var/db seems to contain data about installed packages but since we 
don't back up /usr (when doing a minimal backup) we have to reemerge 
everything and these data should be regenerated automatically, don't you 
think?

I'd add /proc/config.gz to save the kernel config.

For now I think I'll do /etc, /root, /home, /var/lib/portage/world,
/usr/src/linux/.config, and anything specific I might need in
/usr/local.  What else am I missing out on in /var?  I'm OK with a
full reinstall for now.

I do.  I'm on dial-up so even if they can catch me online, they can't
get anything big.  It's to slow to upload to them and just as slow to
send me something.  26K dial-up sucks but DSL is coming soon.

Where do you guys store your backups?  Leaving backups on a DVD in the
same apartment as the machines doesn't make too much sense to me.
Maybe I should mail em to my parents every week or something?

But where do you put the USB stick?  If my apartment building burns to

Offsite backups are a good idea if your data is important to you. I  
have several servers around the world so setting up rsync mirrors is  
pretty painless. Then I burn to DVD remotely.. (I have trained people  
enough so that when the tray opens they replace the DVD with a blank)

You might want to look at doing a stage 4 backup and then sending  
that file to one of those online storage services. A quick google  
shows there are many out there offering 2-25GB of free storage. There  
are some non-free services designed specifically for backup where you  
don't pay to upload but do pay when you want to get your data (which  
given it is a backup I assume you would be highly motivated to pay if  
a restore is required) A few months back I looked into Amazon's S3 to  
automate offsite storage of backups. I never implemented anything  
though.

I would encrypt anything sent to one of those online storage services.

I can't believe you actually asked that. Think, man, think. 

Here's some ways to start:

Leave it at your mum's house where you have dinner every second day
Leave it at your girlfriend's house
Leave it in a safety box at the post office/your bank
Leave it at a friend's house
Leave it in the desk drawer at work
Hang it off your keyring so it's always on your person
Mail the data to your gmail account
Upload the data to your off-site web/ftp/whatever server
Store the backups in your car boot

Encryption yeah.  How do you encrypt your stuff?

I use rsync.net, offsite backups using duplicity for GPG encryption.

Yes, mounted read-only. It avoids accidentally copying a new kernel

snip...

Just my two cents worth here. Often I find a need to generate a duplicate of 
an existing gentoo installation and to ease the build process I run this 
script via cron...

#!/bin/sh

rm  /portage.list/*.*

emerge -pe --color=n system > /portage.list/system.list
emerge -pe --color=n world  > /portage.list/world.list

Basicly it generates a list of installed ebuilds for both the system and world 
model.

In my normal backup routines I add /portage.list... A great way to help 
rebuild an exact duplicate of an existing gentoo box.

Cheers...

Rather than backup MySQL's or Postgres' binary storage I prefer to use the 
relevant tool (mysqldump, pgdump[all]) to backup the database 
to /root/backups/ just prior to running the real backup job.  This has the 
advantage that you can generally restore onto any version of the database 
server, rather than the specific version that was running when the backup was 
taken.

I'm not 100% sure but I thought this method of dumping the database is the 
only way to guarantee consistency of the snapshot without having to stop the 
database server for the duration of the backup.  From what I understand when 
backing up a live database Postgres guarantees the consistency using MVCC but 
MySQL may be a little less careful if INSERTs/UPDATEs happen during the 
backup.  For keeping a hot-spare failover database server closely in sync 
with realtime changes I'd suggest Slony1.

Unless the database contains blobs I prefer to dump as plain text INSERTs and 
compress using gzip patched with --rsyncable support which leads me to...

After backing up the database I /always/ backup to a remote machine,  
sometimes two, using rdiff-backup.  It does point-in-time recovery and 
supports ACLs and xattr.  The backup is not in some odd file format; it's 
stored in a subfolder of your filesystem just like any other tree of files so 
it is instantly available.  A subfolder called rdiff-backup-data stores all 
the rollbacks and also all the acl/xattr/other metadata so the destination 
filesystem doesn't need to support them. There was even a GSoC project to 
provide a FUSE interface to mount the backup folder as it appeared at the 
time of some previous backup.  This is all /very/ nice for when used in 
combination with Linux-VServer.  With a little thought about XIDs you can 
start a backed-up VServer on your development box ;-)

This is the essence of what I run in a cron job on the machine needing to be 
backed up:
#!/bin/bash

#/root/backup_mysql.sh
#/root/backup_postgres.sh

mount /boot > /dev/null 2> /dev/null

Why not just backup the world list itself, /var/lib/portage/world? Your
method doesn't distinguish between packages in world and their
dependencies, emerging from this would result in a screwed world file.

The system list is contained in your profile, so you just need a note of
where /etc/make.profile points, which you will already have is you
backup /etc.

It doesn't have too. The files I listed plus a backup of /etc is all you

So how do you create your world file? And why do you need a list of
system files when you have already backed up /etc?

However, don't exclude files you want, such as .bash*, .xsession, and
so on.  Generally these files aren't large and are important to the
private storage of uesr-specific info for many programs.

BIND, Apache, various mailing programs, at, Xauth, logs if you want to
know what happened on a particular computer six months from now (hard
to foresee this kind of thing).  I think you can clear out /var/tmp if
you wish.  Also many of the logs can be cleared and such.  After
clearing all the data you don't need (be careful; some data is
important to portage), you shouldn't have too much more than a few
hundred megs, pretty much all highly compressable text.

Don't forget to back up stuff that can help you rebuild the system
quickly.  Like /proc/config.gz, or better yet just the kernel and
modules you need so you don't have to rebuild at all or generate the
sources.

Another thing that I think is highly valuable to back up, and very
often ignored, is the output of 'fdisk -l'.  If your drive dies it's
very nice to have a reminder of how it was formatted.

In order to be able to restore a system (relatively) quickly, I use the 
appropriate fs dump tool (xfsdump in my case) to make level 0 backups of 
/boot, / , /usr, /var after a major configuration change (e.g emerge 
--sync;emerge -u world), along with output from df -m. This does not 
take too long (/usr does take a while), but really speeds up a restore 
(I have sufficient packages installed to make an emerge world take > 10 
hours).

For a modern server with minimal software actually installed, the time 
aspect for this method may not be too different from an install from 
scratch, but it also guarantees that the restored system is the same as 
it was before (modulo last backup obviously), which can save a lot of time!

Cheers

Mark

P.s : Actually rebuilding from these saved dumps requires a little 
thought - I'll post the steps if anyone new to dumps is interested in 
using this method  for themselves.

It certainly does, but I'm quite sure it's not what you want. For me at
least losing all my carefully customized stuff in .mutt, .gnupg,
.bashrc, .vim etc. would suck asinine reproductive glands.
It's usually all text anyway that compresses very well.

You might also want to have a look at "dar", it will alow you to specify the

[gentoo-user] Backups...

[BRM]

Well, now that I've got my systems cleaned up, and KDE3 removed, I'm tackling another project I've been meaning to do - backups.

Here's my basic plan:
- I've got a directory on my server that I want to synchronize several systems with (some linux, and one Windows).
- I want clients to push the backup; and not the server to pull it.
- Clients may backup more than once a month.
- the server will receive an additional backup itself once a month which includes all the client backups (may be more often, not sure).

At least on the Linux Systems, I've settled to using rsync for the backup - easy enough to do. I'm already running an rsync server for hosting portage, so it's relatively trivial to add another rsync module to support that way, though I'm not sure what the best way is.

rsync in attractive since it will do delta transfers to keep things in sync; though if I could use scp the same way I probably would since I would just have to setup appropriate keys.

Any how...I setup the rsync daemon with a read-write section. Tested it, and it worked. But I'd really like to have it secured - I don't want anyone to be able to read/write to it. So I tried adding the following:

[backup]
     uid = <backup user>
        gid = <backup group>
     path = /path/to/backup/repo
     read only = false
     list = false
     auth users = <user>
     secrets file = /path/to/rsyncd.secrets

The rsyncd.secrets is simple:
<user>:<8 digit password>

If I don't have the last two lines (e.g. auth user, secrets file) then I can write to it.
Otherwise I get an authentication error:

@ERROR: auth failed on module backup
rsync error: error starting client-server protocol (code 5) at main.c(1503) [sender=3.0.6]

I'm uploading via:

rsync -a --password-file=rsync.passwd someTestFile rsync://<user>@host/backup/extra/path/

rsync.passwd contains the same <8 digit password>, nothing else.


I've already checked file permissions - the entire directory structure under /path/to/backup/repo is owned by <backup user>:<backup group>.

What am I doing wrong?
Is there a better approach?

TIA,

Ben

Now, emerge / equery  will not even show up on a command line.
Most of the time I'm getting an error:
error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory

Running on my other system I get:
equery b libstdc++.so.6
 * Searching for libstdc++.so.6 ... 
sys-devel/gcc-4.5.4 (/usr/lib/gcc/x86_64-pc-linux-gnu/4.5.4/libstdc++.so.6 -> libstdc++.so.6.0.14)

env-update - doesn't work either

I ran into this and I think I ran this:

gcc-config -l

And make sure a compiler is selected.  If not, do gcc-config <number of
one you want to use>  Usually that is the highest one but could depend. 
Either way, one should have a "*" by it like this on mine:

root@fireball / # gcc-config -l
 [1] x86_64-pc-linux-gnu-4.7.3 *
root@fireball / # 

I hope that helps, if not, I'm sure other ideas will come along soon.

I tried to set blindly gcc to active one: "gcc-config 1" but I get the same error 

 * gcc-config: Could not get portage CHOST!
 * gcc-config: You should verify that CHOST is set in one of these places:
 * gcc-config:  - //etc/portage/make.conf

It is a new installation on SSD and it is broken. 
I can't proceed with gcc upgrade/setting, in fact my system is currently broken.

You do not have an /etc/portage/make.conf file, or you have not configured the 
default with the correct settings?

Follow the installation guide and you should find your way out of there.

"make.conf" can be in /etc or /etc/portage mine is in /etc

That is thw wrong location, it is only provided for compatibility with
old installations. /etc/portage is the preferred location and the
settings in the make.conf in there will override yours.

I moved /etc/make.conf to /etc/portage/make.conf rebooted the system but it doesn't help.
Something went wrong during compilation.  

Howto initialized GCC environment from bootstrap?

Check beneath /etc/env.d/ld.so.conf.d and ensure that there is a file 
defining the appropriate paths for your current version of gcc. Here's 
how it looks on my system:

   # cd /etc/ld.so.conf.d
   # ls
   05binutils.conf  05gcc-x86_64-pc-linux-gnu.conf
   # cat 05gcc-x86_64-pc-linux-gnu.conf
   /usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/32
   /usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3

Once you have made any necessary changes, run ldconfig.

Thanks Kerin, for the pointer.
I think I have a bigger problem, and don't know how to fix it.

Yes, I have the same file /etc/ld.so.conf.d
# ls 
# 05gcc-x86_64-pc-linux-gnu.conf
# cat 
/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/32
/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3

However, those directories are empty (only one file):
# ls -al /usr/lib/
libbrcomplpr2.so

On my other working system this directory "/usr/lib/" contain about 2020 files.
What had happened?  

After emerging some files and system I was running command: fstrim -v / (as the disk is SSD).
Could it have something to do with the fact that these directories are empty?

Is /usr/lib an actual directory or a symlink? Assuming that you use a 
stock amd64 (multilib) profile, it should be a symlink to lib64. If you 
find that it is a directory and that you also have a lib64 directory, 
try the commands below. You can skip the busybox and exit commands if 
you are doing this in a chroot rather than on a live system.

   # busybox sh
   # cd /usr/
   # mv lib lib.old
   # ln -s lib64 lib
   # exit

No. Using fstrim does not delete files.

This is not pertinent to the matter at hand. Even if make.conf cannot be 
sourced, CHOST will be sourced from the profile and portage is perfectly 
capable of functioning.

There is no need for a user to define CHOST. At best, it is a no-op and, 
at worst, the user may screw up and define it in such a way that it is 
at odds with the profile.

The error message from gcc-config isn't particularly helpful because it 
falsely implies that make.conf or the "active environment" - as opposed 
to portage's environment - are the only valid sources.

Kerin you are a magician! THANK YOU!!!
Yes, it worked.  Everything is back to normal.

I can still not comprehend what had happened :-/ why all of a sudden in the middle of compilation it all vanished.

Were you doing anything outside of portage that may have had a hand in it?

Incidentally, you should move libbrcomplpr2.so to /usr/lib32. Some 
googling suggests to me that it is a library included in a proprietary 
Brother printer driver package. You can use the file command to confirm 
that it is a 32-bit library.

I was logged in over ssh in one terminal, compiling "xsane"
and logged in, in another terminal and was installing brother printer driver (without emerge) manual installation.
I followed my own instructions from: 
 http://forums.gentoo.org/viewtopic-t-909052-highlight-brother.html?sid=1ba0b92db499262c6a74919d86c6af43

I run: 
tar zxvf ./hl5370dwlpr-2.0.3-1.i386.tar.gz -C / 
tar zxvf ./cupswrapperHL5370DW-2.0.4-1.i386.tar.gz -C / 

Could be that one of this script messed up the links.
If so I don't know how could it happen. Looking though "history" these are the commands I run:

 305  tar zxvf ./brhl5250dnlpr-2.0.1-1.i386.tar.gz -C /
  306  tar zxvf ./cupswrapperHL5250DN-2.0.1-1.i386.tar.gz -C /
  307  cd /usr/local/Brother/cupswrapper

I read your forum post and can see that you're (dangerously) extracting 
directly into the root directory and that this is among the contents of 
the archive:

   ./usr/lib/
   ./usr/lib/libbrcomplpr2.so

I posit that tar clobbers the /usr/lib symlink, converting it into a 
directory because that is what is stored in the archive.

Ergo, use the --keep-directory-symlink parameter.

Excuse the fact that I am replying to myself, but I must also stress 
that the library does not belong in lib64. On a 64-bit system, you 
should adapt your process so that the library ends up residing in lib32, 
not lib64 (by way of the lib symlink). The software will not be able to 
function correctly otherwise.

Thank you again, I've already modified the line (so hopefully nobody else will get caught in it):
eg. tar --keep-directory-symlink -zxvf ./hl5370dwlpr-2.0.3-1.i386.tar.gz -C /

Thank you again. 
On a different subject.  Do you have a good pointer on how to backup a system.
I just had a HD crash so I selected a replacement SSD and I'm re installing the software.
I had backup of /etc/ and /home but I've missed all other settings eg:
/boot/ kernel config and other files and are not in /etc directory like: hylafax setting etc.

Is there a way to keep backup of all those configuration files that are manually edited?

Did it even occur to you at all to type that exact question into a
search engine and see what comes back?

That only returns 18 packages and you're missing most of the ones in app-
backup/.

Try:
eix app-backup/

That gives you 44 to choose from.

Alternatively, copy every file to a usb-disk and manually confirm they are all 
identical?

Well, I first used eix backup.  My thinking was this, if one searches
first for something with "backup" in it, they should notice a lot of
apps in the app-backup category even tho they might not know it existed
before that.  At that point, pot of gold with this:

eix app-backup/*

Thing is, he may not have eix installed.  :/ 

Either way works tho.  :-D 

Me, I just use rsync and call it a day.

And if you then need to ask a question on a different subject, please
start a new thread. It's still thread-jacking if the thread you hijack is
one you started.

Great. If you have the time, explore to integrate your information
into the wiki.gentoo.org. In fact you can start your own brother
wiki page on wiki.gentoo.org.....


Also, just so you know, Gentoo folks routinely use rpm as as
a source for ebuilds. I can dig out some links, if you like
or better yet, others can post those links and relevant urls....


hth,
James

That would be a good idea, if only I could find some time.
Restoring the system is a slow process. Even though I have most of the backups; I still improving it as I restore it.
Making backup of these file that I manually changed.
