This will start off a very vague question as I am not sure the amount of information you will require.
We have been having a lot of issues running our backups. Failing most nights or just running forever. A full backup of our file server takes over 56 Hours.
Because of this we changed our backup schedual so we run all our servers to a disk during the night and then during the day move it over to the Tape. We use LTO3.
The problem we are having is that LTO 3 has a maxiumum speed of 216GB/H while the maximum speed we are currently getting is 118GB/H on average. We are losing 97GB/H. This is causing us some issues as we keep running out of time every day.
The server is
Intel X3.6GHz 2MB 370/380 G4 Processor
HP 4GB REG PC2-3200 2x2GB DDR
Backup Exec 11D
HP StorageWorks 1/8 G2 Ultrium 920 Tape Autoloader
SCSI cable connecting the two.
Any ideas where to look to try and speed this up?
Thanks in advance.
