Installing EvoBackup
|
|
====================
|
|
|
|
Backup server side
|
|
------------------
|
|
|
|
1) Git clone the project (i.e in /root/evobackup).
|
|
|
|
2) 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).
|
|
|
|
3) 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.
|
|
|
|
4) 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.
|
|
|
|
5) 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
|
|
-----------
|
|
|
|
1) Git clone the project (i.e in /root/evobackup).
|
|
|
|
2) 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!
|
|
|
|
3) Install configuration files.
|
|
|
|
```
|
|
root@client1:~/evobackup# install.sh client
|
|
```
|
|
|
|
4) 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.
|
|
|
|
5) 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 backup using rsync filter rules in conf.d/include.cf
|
|
* General config in conf.d/cron.cf
|
|
|
|
6) Connect to the OpenSSH chroot for the first time and accept the fingerprint.
|
|
|
|
```
|
|
root@client1:~/evobackup# ssh backupserver.mydomain.tld -p 2222
|
|
```
|
|
|
|
7) 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. |
