You might want to go with a pair of 146Gig disks, so you can avoid
having to do this again in 6 months or a year.
 
if you configure both tapes then those two barcodes must always be in
the robot.......the barcodes, but not necessarily the tapes.
 
What I've done in the past is, say for instance you have tape 000010 and
000020 as your catalog backup tapes, On Monday, I pull 000010 and swap
the label onto another tape....on the removed tape, mark "Media ID
000010 Catalog Backup Dec 11th" then send it offsite with a return date
for the following Monday...on Tuesday, remove 000020 and swap the label
onto another tape, on this removed tape, mark "Media ID 000020 Catalog
Backup Dec 12th", etc, etc, all week long.....untill next Monday, you
recieve the Dec 11th tape back, then you swap it with the 000010 tape
that comes out next Monday, so you've got a few copies, of the last few
days, if you have a bad piece of media, and you still alway have 2
copies in the library.......
 
 
I did this with DLT tapes when you could swap the labels....Never
considered how I'd do it with LTO tapes with the sticky labels, as right
now, I just replicate the catalog volume to another site, and alternate
catalog backups to two tapes, one local and one offsite, over DWDM.
 
I suppose if you can't change the tape labels, you could just use a half
dozen tapes, and update the catalog backup configuration when you change
tapes.

        That's was great help guys. Thanks a lot. I'll be adding 2 new
disks at the end of the day just to be on the safe side and I plan on
backing up to a second tape. Is there any need to be removing any one of
these tapes to my remote site or should I just keep these 2 tapes in the
library at all times?
