Offsite tape storage?

I just recalled (no pun intended) that when I was last employed, we used
Recall, out of San Jose.
They got bought by Brambles, I think -- a bigger company from Oz.
I had a certain amount of challenge getting things set up the way I
wanted, and there were occasional glitches, but overall, they were
OK to work with (from my limited experience directly dealing with
such folk).
What I had set up -- in case it helps any -- was that we would have
3 canisters; they were to be rotated rather as a juggler might:
* At any given moment, unless we actually requested the canister to
do data recovery, at least one (usually two) canisters were in their
storage.
* At any given moment, at least one (occasionally two) canisters would
be at our place of business.
* Our "normal" backup schedule was "interrupted" on Sunday. Normally,
we used AMANDA, and set things up to let AMANDA schedule backups as
appropriate -- but only Monday - Saturday. On Sunday, I had AMANDA
use a different configuration, one that did a full backup of
everything, but did not record (in /etc/amandadates) that a backup had
been done (so no incremental backup would be made based on this full
backup).
* On Monday (or early Tuesday, if Monday was a holiday), I would put the
newly-written tapes in the canister we had in-house at the time, and
fill out the "transmittal form". [This is a clerical task, and as long
as someone you can trust who does it, it need not be done by
someone with any special technical skills.] The transmittal form
specified that the canister was to return in 2 weeks. (They always
required that the date of return be specified. Given how easily I get
confused by dates & times anyway, this contributed to about half of
the confusion and mistakes we saw.)
* Once per week, on Tuesday, their courier would select one of the
canisters they had in storage (it would always be the one that had
been there the longest, but they just went by canister number and
the date that it was supposed to be returned), bring it to us,
and pick up the new canister (for a 2-week "vacation" in the San Jose
storage facility).
I never did have occasion to test their timliness for providing the
canister in the event of an emergency recall, so I cannot comment on
that.
I hope this helps.
Peace,
david

consistent with reliability. I recommend FreeBSD for reliable systems.
