Oracle backup failing

[Waqar Razi]

I have just observed that one of the database backups are failing. Here is the error log:

Have you verify your tape? its in working condition?
try with another new fresh tape to take backup

also compare tape capacity and your backup size.

if you dont have new fresh tape try to verify this existing tape with dd command, hope this will help

Error:

Begin tape copy of ARC# 14 /ora_backup/prev_0/mmtest/export 02:12:22
tar: *: Cannot stat: No such file or directory

FATAL - The tape copy of /ora_backup/prev_0/mmtest/export 02:12:24 FAILED


Possible cause:

WARNING - The directory /ora_backup/prev_0/mmtest/export has nothing in it

I don't know what backup software is this and you should review all messages and try to identify the reason of that on your server.
