Backup Compression Rate & issues
Hi
i'm using symantec backup exe 12.0 with Service pack 5. We are having HP ultrium LTO 448 backup drive.
For the last 4-5 months when i backup data to the tape drive the compression rate is 1:1 on 400 GB tape and the data saving on it is just around 100 GB and the tape becomes full.
Normally i had around 240 GB. so now i have to use 4 tapes instead of 2 tapes.
We also have a B2D backup which is done successfully without any issues. .
can someone help me on this ?
Thanks
You should also clean the tape drive. It could be that the tape head is dirty.
When you run the LT&T utility, make sure that all the BE services are off and that you select the write test.
Also, click on each of your tapes and check the error statistics. If some of them are new and are showing excessive errors, then it is time to change the tape drive, even if it passes the LT&T utility test.
