Backup and Disaster Recovery

A good backup is the last line of defense. Malicious attackers can fubar your server, but if you have a reliable and tested backup solution you can recover.

Linux and AIX backup advantage:

emergency boot from small media
automatable disk partition and format utilities
full system restore from emergency boot environment
Linux emergency environment is customizable

Solaris, Irix problems:

no easy restore from emergency boot environment
geared to a reinstall followed by restore from backup media

On UNIX the only commercial backup software I have seen work reliably is BRU.

BRU is fast, small, reliable, cross platform, AIX, IRIX, Linux.

Currently I use Star to backup portal. It appears to work pretty well, you can find it here:
