Hi team,

I have backup pieces on the mount point which i do tar with the help of -

tar -cvf DB_$dd.tar DB_* c-*

It has completed the tar but i have seen if the backup pieces size are more than 8GB it gives an error like - tar: read error: unexpected EOF

So, i have added - tar -cvEf DB_$dd.tar DB_* c-* and it done successfully but now again i am getting the same error like -
tar: read error: unexpected EOF

And the backup pieces files size is 150GB so, pls let us know how i can make a tar for this huge size .

thanks

Basically, due to limitations of tar, you'll probably need to use one of the splitting techniques mentioned there.

The other option is to set a cap on the size of your backup pieces when performing backups.

Hope this helps.

Well...I found *this* in the links in the thread:

tar cvf - files_to_archive | split --bytes=4500000000 -a 3 -d - prefix

That looks pretty close to me...

We dont want to spoon feed you :-)

                             _
                             / \
          _..--"""""--.._    \_/
         /,_..-------.._,\    |
        |  `'''-----'''`  |   |
         \               /   / \
          '.           .'    | |
            '--.....--'      \_/

Consider using afio

If you are on a Unix/Linix/AIX system can you try afio
It does not have the limitations of tar AND it has the advantage of cpio where each file saved is independant of the others ie if one file is corrupt you have not lost the whole archive
it can be found at https://github.com/kholtman/afio
