Hi ! Linux Expert

I have a problem with my tar backup. Appreciate if anyone can help.

I am using the following multi archieve backup command.
tar -cMpf /dev/nst0 $SerPath$DIR


At the very end I received "tar: Error exit delayed from previous errors" then the backup process stop there.

The screen appear as follow:

Well are the error messages true? Have the files changed?

Also, this is nothing to do with programming at all, please choose your forum more carefully next time...

Sory ! If place in the wrong place of forum.

Can anybody tell me where should I post the forum so that people don't get annoyed.

Sorry again ! I am just a poor newbie trying to swim in linux ocean. (mhen ! don't understand why linux is better than window)

i have moved it to the correct forum already.
