Hi Guys
I would like to know what "system" of back up are you using... external hard drive as I have (LaCie...) or Raid...

Please let me know because now I have to manage about 2/4 Tetra of information
Thanks, Thierry

i do my processing on a raid0 array and everything gets backed up to a raid6 array.
i have full copies on both computers.

Thanks and what kind of hard drive ?

I use a WD mybook 1 TB HDD...

I use a WD My Book 2TB drive, works super.

Thanks Guy for your time, I really appreciate

I mirror off to three USB HDs at various locations, keep regular backups with 90 days of retention on a 4TB ZFS pool, and also mirror to a 1TB internal drive in one of my way, way, way off-site hosted servers.

I use the 1TB in my iMac and have 2x 1TB western digital HD.

I keep jpegs on the iMac and raws on 1 HD, The other HD has a Backup of everything.

However you do it just make sure that everything is backed up at least twice. I lost some raw files when my 500GB corrupted so now everthing is backed up twice. Another good thing is to backup on a HD and keep it somewhere else (family, work ect)

Doing also double back up

I have 4 1TB Seagate Enterprise level drives in my Mac Pro. I have 8 identical drives in Thermaltake eSata cases. Each drive gets backed up to its own, dedicated backup drive daily. 1 set of 4 drives stays at work and 1 at home. Once a week I take the ones from home to work and bring the ones from work home.
