Been trying to backup the archivestore flat files and also the ESA catalog directory using Backup Exec 12.5.

Have tried this with compression (both hardware and software) and also no compression, on a DL 380 Server. The backups take an extraordinary amount of time and throughput is as little as 18MB/Min (compare this with our SQL at 3GB/Min). Yes I konw that there is a difference in file type ie lots of small files versus one large one but.............why so painfully slow? It's blowing our backup windows.

This is a disk to disk backup (within the same server).

As per my PMs to you, Iím afraid weíve not got any experience of Backup Exec, though I suspect, as you mention, that itís related to the number of files in the store, and BEís handling of this. You tried NT Backup to do the same and it was estimating well over a day. I am afraid thereís nothing we can do to change this Ė itís a BE/NT Backup issue not an ESA one.

The only thing I can suggest is to back up smaller chunks of data.
