Perl backup application
App::BackupPlan
I have recently uploaded a perl application to CPAN.
Here is a short description, from the application README file
App::BackupPlan is a simple module to perform regular, selective and automated backups of your system. It requires an xml file with the specification of your backup plan, logically divided into independent tasks. The constructor also takes a log4perl configuration file, to customise the logging produced. This can be omitted if the default logging behaviour is desired. By setting up a regular back-up task using cron or similar, and by configuring a backup plan with different tasks, backup frequencies and max number of files retained, it is possible to achieve a regular and incremental backup of different part of your system, without too much trouble.
