Re: BRMS and Parallel Backup

All you really need is a 3573 with dual drives and the same attachment, 
SCSI, fibre, or SAS depending on the TARGET machine.  Often the target 
machine is a different hardware level.  You can have a used 3573 with 
two LTO3 sleds fibre attached for about $3500 - $4000.   Price goes up 
for LTO4 and LTO5  drives but the chassis stays the same.   I have an 
LTO3 and LTO5 in mine to keep tape read compatibility back to LTO1 and 
write to LTO2.   LTO5 can read an LTO3 tape.
