EvoBackup
|
||
|
|
=========
|
||
|
|
|
||
|
|
EvoBackup is a bunch of shell scripts to create a backup server which will
|
||
|
|
handle the backup of many servers (clients). Licence is GPLv2.
|
||
|
|
|
||
|
|
The main principle uses SSH chroot (called "jails" in the FreeBSD
|
||
|
|
world) for each client to backup. Each client will upload his data every day
|
||
|
|
using rsync in his chroot (using root account).
|
||
|
|
Incrementals are stored outside of the chroot using hard links. (So incrementals
|
||
|
|
are not available for clients). Using this method we can keep tens of backup of
|
||
|
|
each client securely and not using too much space.

************

|
|
Server 1 ------ SSH/rsync -------> * tcp/2222 *
|

|
||
|
|
Server 2 ------ SSH/rsync -------> * tcp/2223 *

|
This method uses standard tools (ssh, rsync, cp -al). EvoBackup is used for
|
||
|
|
many years by Evolix for back up each day hundreds of servers which uses many
|
||
|
|
terabytes of data.
