Linux network - backups, logs, push files


Hello,

I have a few quick questions relating to a small (7 server) Linux network...

1) Can anyone recommend a simple centralized backup program? Right now I just run a shell script via cron that tars the important directories (run on each system) and puts them in a directory on an NFS share. The scripts run at a time specific to each system, every night. Two hours after the last backup should have finished, another script mirrors the NFS share to an NFS share on another system. Once a week I backup the NFS share to tape. I'm looking for something really simple, that essentially just lets me centrally keep a list of directories to be backed up on each system, runs the backups each night (each one starting when the previous one finished) and puts the data on the two NFS shares. An easy CLI script to handle the weekly tape would also be nice. Essentially, my problem is that given each backup is 1-2Gb, AMANDA is a bit heavyweight for me, and certain directories (and MySQL dumps) need to be done fully every night.

2) So, I've moved databases, web server, mail, storage/shared homes, and monitoring (Nagios, MRTG, Cacti) to separate servers. Now, I have 5 machines with log files that need to be monitored. Right now, I have a script that pulls significant events from the log file on what was previously my one master server, and emails them to me each night. Are there any good programs/scripts out there that will handle log file analysis and emailing, specifically, that can easily achieve a good balance between needed information and false positives?

3) What's the easiest way to push files out between servers? Rsync? I'm looking for something ultra-simple, just for pushing new versions of administrative scripts to my servers.

Thanks,
Jason

for 2) of your question I can recommend 'dirvish' which is a highly customizable backup frontend for rsync. It supports backup expiration by date and can be run with cron.
