Best lowest cost best performance solution I know of and currently use is a seperate winblows maching with 5 removable IDE drives od whatever size you would like... Ours consists of a celeron 800 system with a hardrive for OS and cd drive modem nic and sound (new system priced at $289.00 with a refurbished 17"monitor $109.00 ) and five removable drive bays (under $10 each) and OS drive five 40 gig hardrives for backedup data ($99.00each) and a piece of shareware backup software not expensive. get the hole thing for under $1000
We rotate drives every day and we right now have about 2 months of backup data on the drives and they are about 2/3 full...sweet if you ever got to go back more than a week or so do that with tape and you will spend alot of money on tapes.
We just back up over the network, to the backup server. Simple automated and lowcost and best of all if you want you can do a direct copy of the data, and scan all the files for virus infections... once backed up. Harddrives have a longer life span than tape also....lower cost ofer lifespan..
We back up two nt servers and another linux box and our e-smith server this way and it works great ...the shareware software we use even varifies the data after the entire backup..and it is faster that our old scsi travern tape drives were.
This is the best solution I have come across yet, it works flawlessly on a crossplatform network also..
We dont back up the e-smiths OS daily, we just do the backup to destop feature in the E-smith os and dump that on our removable drive.. but we only do this once and a while since it takes less than 45 minutes to set up E-smith on a system, then just copy the data back to your ibay and it is done..simple, sweet, and cheap... the backup server could actually be slower than we use you could do this with a old 233mhz system easly..
