Slow Duplicates from one library to another

BTW, both libraries are hooked to the same Backup Exec server running 2003 Standard.

Thanks

Make sure that "Single Block Read" is not enabled on the LTO3 (neither single block options hsould be selected)

It looks like none of the drives have "read" options selected, but all have the "write" options checked.

I believe these are the defaults.

I disabled the "write" options on all drives and the duplicate job rate decreased to the 30-40 MB/min range.

I tried again and let it run for a while. The job speeds up after about 10 minutes and reached up to 800 MB/min. and has been gradually slowing down. Currently, it is at 713 MB/min.

Any other suggestions for things to check?

Thanks for your help.

Don't have any more suggestions, sorry

Overnight, the job has slowed to 330 MB/min, which seems typical. Large duplicates (500GB-1500GB) generally start out at a decent rate and slow to a crawl.

Almost sounds like you may have a memory leak.
