Slow Backup and Restore Rates

I am experiencing slow backup and restore rates. What can I do?

When you back up or restore remote servers, Arcserve Backup performance can drop and the transfer rate can be extremely low.

If the backup or restore rate slows only on some volumes, the problem could be due to the number of files on the volume. If the volume has a large number of files in one directory, NetWare performance is compromised because of the way it handles directory caching.

When you request a directory, NetWare "remembers" this request, assumes that you want the files in that directory, and allocates memory for this purpose, typically about 20 buffers at a time. However, in volumes with many files in one directory, NetWare slows as it attempts to cache the directory entries for the files.

To increase the buffers, use the NetWare SET command. Change the setting from 20 to 500, as in the following example:

SET MINIMUM DIRECTORYCACHE BUFFERS=500

If necessary, you can "fine tune" 500 to a smaller number.
