Fadia,
Have you tried man tar to see what probably suits things that you are trying to accomplish?

Hello Fadia,

could you please give us some more context on your problem. What are you trying to do and what type of error do you receive? Disk to disk tar, tar to a tape...?

Greetings, Martin

Hi fadia,
If you mean that you need backup through several media devices, you can try:

If you mean "more than 2Gb files" by large files, tar have a limitation and cannot store thoses files.

If you have such files, you must use another backup program. I would suggest arkeia :
http://www.arkeia.com/ which is free for a linux server backuping itself. It handles correctly 2Gb on any filesystems and has a command line interface as well as a GUI. It can do from one-shot-backup to complex backup strategies with incrementals, retentions and so on...

Hello,

the following

https://listman.redhat.com/archives/phoebe-list/2003-February/msg00832.html

seems to indicate that the 2GB file limit for tar was liftet latest with RH 8.

Greetings, Martin

To follow up on my self. The 2 GB file size limit was liftet for Gnu tar with release
1.13. See here

for details.

Have you tried another tape?

That's standard can't-write-to-the-tape errors, not tar.

Had it this morning on a DAT40 drive. Run the cleaning tape through, try another tape, see if the problem persists.

i change the tape and i get the same error i want to know what to do for that and for more i do the backup using dump and it gives me also error
