Now I have two main questions in mind: what to and how to back up on gentoo most efficiently. 1.

Erm..okay, I am gonna say, what magic I want and then ask your way. I first started making gzipped tar balls as follows: tar czpf /media/backups/userA-`date +%Y.%m.%d`.tgz -X userA-excludelist /etc But these can get huge especially for home dirs. I also want safe dvd copies. Though I can find enough space on the external drives, I don't trust them any more. See above..sigh..(No I recovered about one third of it with testdisk/photorec which names them as file000001 file00002.. and half them are zero sized.. which quite justifies my agony) Here is what I wanna do. I want to have only one big backup for, say, userA-2010.08.07.tgz and other small backup tars containing only the files/folders that were modified since last update, 2010.08.07, as userA-diff-2010.08.14.tgz, userA-diff-2010.08.21.tgz, userA-diff-2010.08.28.tgz etc. Now if I want to take the userA back to the future, 2010.08.21, I want to do it by first extracting the huge tar userA-2010.08.07.tgz and then the tiny backup userA-diff-2010-08-21.tgz. But the thing is I don't know how to do this. I am hoping maybe you can tell me how to of it as well as a better way of doing backups. By the way, since I want dvd backups as well, and I want to use +rw dvds so I can overwrite old backup after a while, what is best way of ensuring the integrity and safety of them. Is it a good idea to use truecrypt containers? Or nothing tops signing and encrypting with gpg?

Hello all,

My first post on the list. I = thought I would start with something that I started
to think of a= s 'essential' after losing 90GB of data. Now I have two main
questions in mind: what to and how to back up on gentoo most efficient= ly.

1. Apart from users' home directories and = the followings, what should be backed
up on a gentoo machine?=A0<= /div>
/etc/portage/
/root
/var/lib/portage
...= ?

2. Erm..okay, I am gonna say,=A0what magic I wan= t and then ask your way.
I first started making gzipped tar balls= as follows:

tar czpf /media/backups/userA-`date +%Y.%m.%d`.tgz -X u= serA-excludelist /etc

But these can get huge espec= ially for home dirs. I also want safe dvd copies.=A0
Though I can= find enough space on the external drives, I don't trust them
any more. See above..sigh..(No I recovered about one third of it with = testdisk/photorec =A0

Here is what I wanna do. I want to have only one big ba= ckup for, say,
