[nflug] backups on an nfs server ..on and on

[Richard Hubbard]

Big question... why tape?  It's slow, amazingly unreliable, and very expensive.

Consider these tape drives (no tapes... just the drives)

Now consider these combinations
First a  hard drive, for about the cost of a tape (not the tape drive, just the tape)

next, an external enclosure...

so you could get a bunch of external, "usb"  hard drives (which is also automatically recognized by most distributions of linux) that is fast, inexpensive, and actually more reliable than tape. 
If you are worried about damage due to dropping, etc. Tape cartridges are just as vulnerable as hard drives, and since the medium in a tape cartridge is exposed to open air, is more susceptible to just dying of old age.

I'm going to have to find an external scsi tape drive that is comaptible
with linux, the one that I was using with what used to be a win2000
server seems to be only semi compatible with linux it is an external
scsi Dell PowerVault 110t

I am able to rewind the tape but cannot write to it, I think Cyber was
having the same kind of problem with an LTO??
