Are you getting only 410GB on a single LTO4 tape or is your job failing when it writes more than 410GB?  If it is the former, it could be that you are compressing data which are already compressed and end up with more data than you have started.

...check your compression settings on the tape and see what the ration is. Report back on that.

Thanks!

Hi,

Job is success fully completing and there is no failures but only think is its writing 410 GB only and its wating of space and tapes.

What kind of data are you backing up? Like are they Image files or any form of compressed files. Also, I Backup Exec, does the Tape show full. Was this job set to overwrite when it was started or did it append to an old tape?

[RameshM]

Nomal Data files only(docs,PDF,Excel and jpeg and archive files(.nfs files)

[RameshM]

Ration is 1.1

Thanks

...then make sure you're using compression in the actual job, and that you're using the Symantec drivers for the tape drive (use tapeinst.exe to install them).

You should also download HP Library and Tape Tools and install it. Stop the BE services, put in a tape that can be overwritten, and do the compression test. Check this, and then do the device diagnostic tests to rule out physical hardware issues.

Thanks!

jpegs and archive files are already compressed and when you compress them, you might end up with more data than what you have started with.

To test that your compression is working, create a directory with only text files and back this directory up.  You should be able to see some compression if your compression is working.
