VE Backups [message #1888]

Anyone got any little scripts to run backups of ve's on the server?

At this time, I'm just doing a rsync of /vz/private and the vz-scripts directory to a 2nd drive.

Any suggestions would be appreciated.

If you backup your VPS'es on the same machine, you can do it more simple:

By cron, on hardware node.

# cat vps_backup.sh

#!/bin/sh
vps_id=$1
vzprivate="/run/vz/private/"
backupdir="/run/backup/"

cd $vzprivate/$vps_id/;
tar czf $backupdir/vps/vps.$vps_id.`date +%a`.tgz .

#crontab -l

# Backup
00 03 * * * "/run/backup/vps/vps_backup.sh 109"
00 04 * * * "/run/backup/vps/vps_backup.sh 114"
00 05 * * * "/run/backup/vps/vps_backup.sh 111"

Yes, that would work, but alot of work when you have quite a few ve's heh

Also i would have to manually go remove old backups unfortunately.

`date +%a`.tgz . will create weeks backups , so you need not to remove something manually Smile

# ls -la /run/backup/vps/vps.114.*

Any way to do it where it will do all the ve's without having multiple crons?

And maybe keep less amount of days?

It is not complex Wink

#!/bin/sh
vzprivate="/run/vz/private"
backupdir="/run/backup"

for x in `ls $vzprivate` ; do
        cd $vzprivate/$x; tar -czf $backupdir/vps.$x.`date +%a`.tgz .
        done

And you could start it by cron so often, how much it is necessary for you. Also you could use nice for downturn of a priority of it.

What about keeping less days than a week, is that something simple?

Yes it simple. But, I'm sorry.

In this example backup's will be done every night, not a week.
Just because it has name with day of week, it is stored only week, until it will be rewriten.

You guys should really consider doing rsync instead. Your server loads would be dramatically less during a backup

for i in `ls /vz/private/`; do rsync --progress -var /vz/private/$i /backup/daily --delete-after; done

Then if you wanted weekly run this once a week:

for i in `ls /vz/private/`; do rsync --progress -var /vz/private/$i /backup/weekly --delete-after; done

That should do the trick, but keep in mind you might need some insane disk space to do this, depending on how many vps you have on the system.
