Hi All

I am sure this has been discussed multiple times.
I have searched the forum and found nothing like my problem.
I have windows server 2003 it runs a incremental backup everyday.
but on saturday it runs a normal(full) backup. during the week it runs fine.
on the weekend it fails and gives me the E: is not a valid drive, or you do not have access.
I have checked security and NTBackup user has all the permissions for drive E:
and so does Backup Operators also. any ideas what else i should check?

Thanks

Are there time restrictions on these accounts that allow logons during the work week, but no access during off hours?

Member Avatar for dvr

No time restrictions, this also was working fine for about a year

What is the E drive then? iSCSI, local disk, other?

Ok weird... During the backup window, can you sign into the host and access e:?

Any other tasks on this host that might 'shuffle' drive letters?

Member Avatar for dvr

no nothing that changes drive letters.
i haven't tried accessing it, because it usually starts the full backup around 2am.
however i have signed in and made sure that all the drives are connected.
when this first started happening i rebooted the server every saturday and that seemed to fix it.
now it started doing it again and i still reboot the server.
frustrating dealing with backup issues.

How about any event log entries at or about 2 AM? It's an odd issue...

Member Avatar for dvr

didnt see anything, I always check the event logs.
i attached a small clip of the event log from last weekend.
when i open the event log error it says "End Backup: E: Warnings or errors were encountered consult backup log"
which says E: is not a valid drive, or you do not have access.

Well, then I guess verify the account that the backup is running with, and test it manually during that time window. That would be my next step.
