This is (generally) not good advice. The hardware compression performed
by tape drive technology achieves faster, more efficient compression;
the TSM server itself has nothing to do with it.
This varies greatly with the data, of course. I'm seeing compression
ratios of 4:1 with email, which is mostly plain text with a lot of blank
space characters. MIME attachments usually compress 2:1. Many binaries
are already compressed, such as jpeg images, and do not compress any
further. But on t
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
