Could you give me ex-developer Rob's home directory from tape from
last January 17th please?
Oh wait, I mean Jan 17 of 2001.
And we need a restore of that Sparc 2 machine we had in 1995.
There was some code in /usr/local/src/ and that's the only place
we KNOW where it is.
Tapes are not drives.
It is not practical to slide 40 drives/night into your backup
array and ship half of them to IronMountain.
That said, my S.O. deals with 200 Terrabytes of data (many
computers, many RAIDs). They don't/can't backup most of that.
