synchronization

[liquidmonkey]

hi there,
i just bought a WD 500gig external drive and will be using it for backups of certain folders.

i'm wondering if there is an easy way to do a backup with the imac OR if there is any synchronization software on the imac to do this??

if not, which is a good and free synchronization software that i could use?

thanks in advance
