Hi. I'm backing up a couple of servers to a backup exec 12.5 server running Server 2008 and using an HP Ultrium 1760 with HP LTO4 tapes. All running fine until the 7th - it backed up 941GB of data that night. Since then it's failed consistently. The tapes show a maximum capacity of 781.5GB, which is no compression at all, isn't it? Looking at some of the tapes that haven't been used since the 7th, they've reported compression of between 1.4 and 1.9:1, so I'm guessing this is an issue with the drive or the software rather than the media. Compression's enabled on the drive
I've tried updating the drivers on the tape but I still can't get the tape to accept more than its uncompressed limits. Thanks.
