Backup Exec Issue

[gmonks]

Hi,

 

Okay so I have been trying to work this out for two days now but seem to be getting nowhere.

 

We have a backup that is 312GB and we're trying to put this backup onto a tape. The tape has 400GB when compressed and 200GB native. However, whenever we set the backup to run in backup exec 2010 it stops when it gets 220GB and the tape ejects itself and wants another tape inserted.

 

I'm not sure why this is happening considering the compression type is set to software. When the compression type is set to hardware the tape ejects itself after 198GB.

 

Anybody have any ideas?

 

Any help will be greatly received!

Thanks

 

George.

You're not going to like this, but you probably need a different backup solution if your tapes are 200GB native and your backup is 312GB!

 

Depending on what is being backed up, you may find a lot of it is already in a "compressed" or efficient(ish) format, so possible compression factors will be low.

Well the backup is 312GB and it's not compressed I'm not sure why it's not compressing?

because it's not compressible? jpeg/zip/mpg etc will not be compressed at all when going on to tape, they already are.

 

What's the compression ratio for the job?

Exactly. An extra 20GB is what we used to get when we had 200GB tapes (if we were lucky). That's why I insisted on 800GB/1.6TB tapes on the current machine. Way more than is needed at present, but in a year or two...

Ok thank you both.
