Automatic Backup software

[Markus Kolb]

Hello,

can anyone recommend an opensource backup software which can do
automatic, unattended backups.
I need different backup level support or best would be something with
versioning like Tivoli Storage Manager does.
Of course it needs not to be so great and powerful as TSM.
It would be nice if the solution could manage the backup space with
ftp.
And it should be no huge application.
At the moment I use selfmade scripts in cronjobs with time stamping but
the restore of single files is not very comfortable.
Before I add some versioning and restore help to my backup scripts I want
to have a look at the "world".
A first look at freshmeat and sf.net told me that there is many backup
software out there but it is difficult to find the right one.
So maybe you can recommend.
