I am backing up 2 databases and sending the files/reports
to another server. I have requested that backup files be
deleted that are > 1 day, and report files > 1 week.
Occasionally it fails with the following error, and I
don't know why. Has anybody seen this before?

BackupDiskFile::RequestDurableMedia: failure on backup
device '\\WWSFP1\Data\Backup\WWDB1_db_200309112200.BAK'.
Operating system error 64(The specified network name is no
longer available.).

It sounds like your network has a glitch every now and then OR is the
destination a RAID 5 array ? It could be that writing the large files to
this disk subsystem is causing it to hiccup.

RAID 2. I have tried changing the time on the plan, but
it doesn't seem to make a difference.

I'd go with Allan's first guess. Have you checked the
Windows event logs for network related warnings or errors?
Any redirector timeouts?

I don't see any errors in event viewer around the time

If you checked the SQL Server server, the destination server
and the DC for errors and didn't find anything, I don't know
what else to suggest but for whatever reason, you lose your
connectivity to the other server which is typically network
related.
