Installing EvoBackup
Backup server side
-
Git clone the project (i.e in /root/evobackup).
-
Install configuration files.
root@backupserver:~/evobackup# install.sh
This will create /etc/evobackup and /etc/init.d/evobackup (or /etc/init/evobackup.conf for Ubuntu).
- Set up the first chroot.
root@backupserver:~/evobackup# chroot-new.sh -n client1 -i 192.168.0.10 -p 2222 -k /path/to/rsakeyclient1.pub
This will create the OpenSSH chroot for the machine "client1", listening on port 2222 and accepting only connections from 192.168.0.10 using public key rsakeyclient1.pub.
Tip: If you have already a chroot, you can commit the port option (-p), it will be incremented from the last chroot.
- Handle incrementals by modifying /etc/evobackup/conf.d/incs/client1
Syntax of this file is simple:
- +%Y-%m-%d.-0day Keep actual day
- +%Y-%m-%d.-1day Keep yesterday
- +%Y-%m-01.-0month Keep the firt day of the actual month
- +%Y-%m-01.-1month Keep the first day of the last month
Tip: You can use rdiff-backup in place of rsync, and choose to not use EvoBackup incrementals method. You need to modify the cronjob.
- Set up the scripts which will handle incrementals.
root@backupserver:~/evobackup# mkdir -p /usr/share/scripts
root@backupserver:~/evobackup# cp crons/evobackup-{inc,rm}.sh /usr/share/scripts/
root@backupserver:~/evobackup# chmod u+x /usr/share/scripts/evobackup-{inc,rm}.sh
root@backupserver:~/evobackup# crontab -e
Set this in the root crontab
29 10 * * * pkill evobackup-rm.sh && echo "Kill evobackup-rm.sh done" | mail -s "[warn] EvoBackup - purge incs interrupted" root
30 10 * * * /usr/share/scripts/evobackup-inc.sh && /usr/share/scripts/evobackup-rm.sh
Client side
-
Git clone the project (i.e in /root/evobackup).
-
Generates OpenSSH key for user root (if user root don't have one already).
root@client1:~/evobackup# ssh-keygen
Do not set a passphrase, otherwise you will need to enter the passphrase (or store it using an agent) for each backups!
- Install configuration files.
root@client1:~/evobackup# install.sh client
- Add the zzz_evobackup crontab into the daily cronjobs (recommended):
root@client1:~/evobackup# cp crons/zzz_evobackup /etc/cron.daily/
root@client1:~/evobackup# chmod 700 /etc/cron.daily/zzz_evobackup
Why "zzz"? Because we want the backup cronjob to be the last one.
- Configure the cronjob.
In /etc/evobackup:
-
What to backup using shell scripts in actions.d. By default all scripts are commented out. Un-comment or write your own code, this will be launched before the rsync, using run-parts.
-
What to include in conf.d/include.cf
-
What to exclude in conf.d/exclude.cf
-
General config in conf.d/cron.cf
- Optional, test with sh -x.
root@client1:~/evobackup# sh -x /etc/cron.daily/zzz_evobackup
Updating OpenSSH chroot
When you upgrade you system you may need to upgrade the OpenSSH chroot. To do that launch update-chroot.sh.
root@backupserver:~/evobackup# chroot-update.sh
Then reload sshd daemons.
