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.

A major tool for that is rsync and rsnapshot.

For general theory about it maybe a google search like:

Well pull up a bunch of likely stuff

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.

how can one create bootable CDs/DVDs? Is there a simple way to transfer
GRUB into the DVD/CDs? Or would "dd" of the /boot partition transfer the
whole thing??

The boot process for a CD is very very different than from a hard
drive.  Basically the BIOS has to pretend that the CD drive is
actually a floppy, or a hard drive, for implementing the BIOS calls
used by the boot loader.  Doing a "dd" of a boot partition and writing
that to a CD would not work.

There are several different software packages that can make bootable
CDs, including GRUB.  Ok, it isn't really GRUB that makes the CD
bootable, but mkisofs.  To use GRUB, you have to make a /boot/grub
directory in your CD tree, and copy the stage2_eltorito file into that
directory along with grub.conf/menu.lst.

Then when you run mkisofs, you add the options:

-b boot/grub/stage2_eltorito -no-emul-boot -boot-load-size 4 -boot-info-table

Someone who uses a GUI for CD burning will have to comment on how to
do this without the command line!

Oh, I forgot one thing.  Instead of (hdX,X) in grub.conf, you use
(cd).  For example:

title 2.6
    kernel (cd)/boot/vmlinuz-2.6 root=/dev/hdc

Of course, your kernel must have support for your CD-ROM drive and the
iso9660 filesystem built in...

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

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

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?

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

Yes, mounted read-only. It avoids accidentally copying a new kernel
to /boot without mounting it. that's on the machines that have a

Other data in /var/lib. For example, any databases kept in /var/lib/mysql.

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.

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

.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 
size of every file (and even have a different size for the first file, 
usefull if you want to put a linux rescue install on the first cd)

[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

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?

Come on dude, we aren't here to do ALL your thinking for you.

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.
