That depends -- on the data and on the client.
I've got LTO-1 (100/200) GB tapes and drives. MS-Exchange Infostore backups
are compressed on disk and not decompressed by the client for backup - and I
get full tapes at 101 GB. On the other hand, my SAP/R3 (Oracle) database is
not compressed on the client -- and I get between 485 GB and 521 GB per
tape.
So - you should get at least 190 to 200 GB per tape on the LTO-2; you MAY
get considerably more than 400 GB. We'll be going LTO-2 in five months, and
I'm looking forward to seeing how much SAP database I can fit on one tape.

Subject: LTO tape cartridge(200GB/400GB) stores data 500GB+.
Hi,
Just for clarification, I'm using LTO-Ult tape cartridge having capacity of
200GB/400GB, Tape library 3582L23 with two 3580-LTOG2 drives with firmware
38D0, and devclass was defined with device-type=LTO and Format=ULTRIM2C. Now
the tape is storing more then 500GB of data, Is it normal behavior.
Thanks,
