I created a job in ARCserve 11.5 - SP4 to backup 745GB and then 531GB is that it copies requested a second blank tape (see the screen in print http://i1184.photobucket.com/albums/z336/paulosouza55/please_mount_a_blank_media_to_continue_the_backup.jpg).

It run a Full Erase before starting the backup, but the problem persists.

I am using the Sony LTX400G 400/800GB tape.

Please can someone help me?

Thank you.

I think what you are saying is that you are getting 531gb on a 400gb tape (800 is completely made up based on 2:1 compression). So your stuff is not as compressable as 2:1. Totally normal. I've never gotten over 700 on a 400/800 tape.

First thank you for reply.

With 700GB which tape you got?

Thank you.

I don't really understand your question. The brand of tape has nothing to do with it. It has everything to do with how compressable your data is. Don't think of it as an 800gb tape, it's not. It's a 400gb tape with optional compression.
I personally quit usin tapes as I don't need snapshots on time of financial type data, I exclusively do disk to disk now as tapes have not kept up in cost or size.
