Hi there,
I would appreciate some advice from you experts out there.
I have one library with 2 LTO4 drives and 2 LTO5 drives. All media previously was LTO4 and everything works geat.
We are running low on storage slots and the company I work for will not invest in an expansion unit for our TS3310 library (shared with TSM).
We have two major pools. ONSITE and OFFSITE. I've replaced all onsite tapes with LTO5 media (to allow for more data to be copied to tape, and thus, free up slots) and now, all offsite tapes will be LTO4. Everything is working fine. All jobs write to disk, than disk duplicates to ONSITE and OFFSITE without issue.
ONSITE = LTO5 media (never leaves the library
OFFSITE = LTO4 media (sent out daily)
LTO4 tapes are HCART
LTO5 tapes are DLT (netbackup auto configured this)
My concern is the integrity of data. Will data that is copied from LTO4 to LTO5 media be consistent? Could we potentially run into issues where we recall an offsite tape and the images are bad (due to copying between LTO technologies).
Thanks for any advice you can offer.
