Thank you for the answer, I think that I would make the test the next
week I would hold you with the informed one

When I upgraded from 2.x to 3.0 there were no problems with BackupPC
itself.
I needed to update to a current perl version, and needed to get some
new/updated perl modules using cpan. Read the BackupPC.html file in the
release, looking under "requirements". If you get perl ready first, then
you won't have to see errors coming from BackupPC about missing perl
modules. (I did a global update which took the best part of a day on my
slow Pentium II machine.)
(I don't think that updating perl and perl modules should break your 2.1
installation, but cannot say that for sure. Anyone else know
otherwise?)
The ultimate "minimum of risk" would be to build a new backup server
from the ground up, but I'll assume that is not an option...
If you want to upgrade but be able to go back to 2.1 you can try this...
1) Back up your current installation and configurations.
Here are my files, yours are probably in somewhat different
directories:
Software installation: /usr/local/backuppc/*
daemon startup script: /etc/init.d/backuppc
cgi script: /var/www/localhost/cgi-bin/BackupPC_Admin
Configurations:
/data/backuppc/conf/*
/data/backuppc/pc/*/config.pl
That's the software and configuration files...
If you want to back up the data pool itself, that's up to you,
but I do not believe anything changes in the pool when
upgrading.
2) Create a "test" back up client. Test it to make sure it works under
2.1.
(Or plan to use an existing client for testing.)
3) Upgrade to the new version. (See BackupPC.html)
4) Test with the "test" back up client
5) If you have problems you cannot resolve, restore from the backups
made in step 1.
6) Remove the "test" back up client.
The install script will remind you that there is a daemon program
running that needs to be stopped (and restarted afterwards).
Hey list, did I miss anything?
I hope that helps ~cg
