 Posted: Fri Jan 20, 2006 12:55 pm Post subject: Crontab Script Backup |
 |
|
I have an extra HD mounted that is big enough to hold multiple backups, I'd like to created an automated backup rotation, like 7 or so copies.
Any suggestions?

From the top of my head... sync (rsync ;])

| Code: | NAME
sync - flush filesystem buffers
|
^--- I don't see how that would help...
And the rsync looks a bit overkill for what I'm doing, the hard drive I'm backing up to is *on* this local machine.

what exactly are you trying to backup? (how much data)
How periodical will those backup be?
Do you want to have multiple backups?
Note: rsync is just a mechanism ... it's fairly good if you want to keep one up-to-date backup, done in periods of time. Much better (and safer?) the doing a software raid ;]

How much data? Mmmm... about ~5 Gb worth.
Hrm... looking at this, I only have a 10Gb backup part on this Hd.... thought I had more.
So just one copy, to be done once a month.

Than once again ... I suggest rsync it's really all you need.
If not have a look here: (prolly some useful software)
http://www.linux.org/apps/all/Administration/Backup.html
I gather it's not a commercial server so:
My suggestions if you want to backup data into the same server:
- partition the backup hd so you can have TWO backups (done ,say every 15 days - one on 15th and one on 30th of each month).
- Every month make a backup of your /etc/ and /var/ onto a cd (cd-rw would suffice)
- encrypt your /home and /root partitions (on the backup) if you keep any sensitive data there
<edit>
in my personal expirience backula and cdbackup are nice ... though they may nto exactly suit your needs
<edit once more>

Have a look at rsback http://www.pollux.franken.de/hjb/rsback/
It uses rsync, so it's probably a bit overkill for your needs, but should do fine.

Which directories would you guys say are safely skippable?
I'm assuming /tmp and /proc.... any others?

I have plenty of room on this drive, so that's not the issue.
