Backup Requesting additional media

Our backup keeps coming back saying please insert additional media. I have manually checked the amount of information to be backed up and at most it is only comed to approx 30GB which i dont think is too much for one tape. We are using an HP C7438A driver with DAT72 tapes. the backup software is brightstor arcserve r11.1 running on windows server 2003 SBS. I have already been in touch with CA and was promptly told "support no longer offered heres a free trial for the new version". Can anyone help me with this?

DAT72 Tapes fit 36GB uncompressed or 72GB compressed.

You could try turning on compression on your backups and see if that has sorted it.

Please be aware many formats such as JPG are already compressed and connot be compressed further. If you have a high volume of these you might want to be looking at using a different tape drive, or setting up a storage server to hold yoru backups.

media compression is disabled but the job is set to compress files prior to the backup

ARCserve is intelligent enough to detect hardare compression on tape drive and disable it's own compression. You should also get an warning message saying Software compression disabled as hardware compression is enabled on the tape drive.

Compression depends on many factors. Most common one is type of backup like files backup, DB backup etc..

Try to compare hardware and software compression. ARCServe should give you compression ratio if job is running with software compression.

You can also reduce the amount of data selected in source. Find if you have any duplicate selections.
