I have a Sony SDX-500C tape drive with AIT2 tapes with a stated native capacity of 50Gb and a compressed capacity of 130Gb.
I am running Arcserve 2000 version 7.0 on a Windows 2000 server.
The amount of data to backup has recently risen above 50Gb and is prompting for a second backup tape.
When I set the backup job to compress the data, I get the message w3032 Compression is disabled due to hardware data compression in the activity log.
My question is, if the hardware compression is enabled, then why am I only getting the native capacity of the tape?
Are the tapes specific to software compression only and should I be disabling the hardware compression to be able to do this? What impact is this likely to have on backup job?
