Snapback2 Description

Rsync and hard-link backup script Snapback2 is a Perl module that does backup of systems via ssh and rsync. It creates rolling "snapshots" based on hourly, daily, weekly, and monthly rotations. When it runs for some period of time, you will end up with a target backup directory that looks like: drwx--x--x 81 106 staff 4096 Jan 1 05:54 daily.0 drwx--x--x 81 106 staff 4096 Dec 31 05:55 daily.1 drwx--x--x 81 106 staff 4096 Dec 30 05:55 daily.2 drwx--x--x 81 106 staff 4096 Dec 29 05:54 daily.3 drwx--x--x 81 106 staff 4096 Dec 28 05:53 daily.4 drwx--x--x 81 106 staff 4096 Dec 27 05:53 daily.5 drwx--x--x 81 106 staff 4096 Dec 26 05:53 daily.5 drwx--x--x 81 106 staff 4096 Jan 1 05:54 hourly.0 drwx--x--x 81 106 staff 4096 Dec 31 17:23 hourly.1 drwx--x--x 81 106 staff 4096 Jan 1 05:54 monthly.0 drwx--x--x 81 106 staff 4096 Dec 1 05:54 monthly.1 drwx--x--x 81 106 staff 4096 Dec 28 05:53 weekly.0 drwx--x--x 81 106 staff 4096 Dec 21 05:53 weekly.1 drwx--x--x 81 106 staff 4096 Dec 14 05:53 weekly.2 drwx--x--x 81 106 staff 4096 Dec 7 05:53 weekly.3You might think this would take up lots of space. However, snapback2 hard-links the files to create the images. If the file doesn't change, only a link is necessary, taking very little space. It is possible to create a complete yearly backup in just over 2x the actual storage space consumed by the image.SYNOPSIS snapback2 Requirements: · Perl
