Looking for free backup software that will allow backups across multiple machines [closed]

"Cobian Backup (You want version 9, Amanita)

Free and bloody easy to use
You can access network shares
Supports compression and encryption
Backups history (up to any amount you define)
Supports pre and post backup scripts
Allows for Scheduled Backups
Full, Incremental and Differential backups
Supports Volume Shadow Copy (allows
backups of locked files)
Can be ran as a service or normal
application

(the above is my review) I no longer use Cobian since last year I switched to tape backup. Until then Cobian had been my little underdog gem. I highly recommend it."

rsync has become my favorite tool for redundancy and backing up. If you're a windows user and relying on a GUI, someone else may have a better suggestion.

"Try DriveImage XML:

DriveImage XML is an easy to use and reliable program for imaging and
backing up partitions and logical drives.

Image creation uses Microsoft's Volume Shadow Services (VSS), allowing
you to create safe ""hot images"" even from drives currently in use.
Images are stored in XML files, allowing you to process them with 3rd
party tools. Never again be stuck with a useless backup! Restore
images to drives without having to reboot. DriveImage XML is now
faster than ever, offering two different compression levels.

DriveImage XML runs under Windows XP, Windows Server 2003, Vista and
Windows 7 only. The program will backup, image and restore drives
formatted with FAT 12, 16, 32 and NTFS."
