TAR limitations

Hi,
Can we overcome the tar limitation of backing up files larger than 2GB by any chance. We require to take backup of some DBF files which exceeds this limit.

Regards

Hi,
Why not just use fbackup?

Hi,

i think i read something that the GNU Version of tar doesn't have this 2GB limit. Check at www.gnu.org or at the Software Porting Center.

Hope this helps

Hi

I would agree with the fbackup since HP supports that.

Also it is a lot faster.

Hi

I agree with Steve where possible stay with the supported tools sets. Another alternative is cpio also supported.

cheers
John.

Please don't missunderstand me. My reply points towards your "Can we overcome the tar limitation of backing up files larger than 2GB".

As the others i reconmend staying with the supported tools if possible.

hi,

You can use GNU tar. It is a popular substitute for regular tar, in such cases.

GNU tar will certainly do the trick. GNU tar has more advantages over HP's tar than just the 2Gb bound. It has also builtin compression (gzip) and other very useful options.

Though you all have a valid point that using fbackup is both faster and more widely available for HP systems, there's also some drawbacks to that.

1. It's absolutely unportable to other systems (AIX, Solaris, Linux, ...)
2. The user interface (command line options) sucks
3. It's not backward compatible
4. It is rigid (it cannot deal with other formats)

We've chosen for GNU's cpio, having the widest range of cross system options and portability

Hi ,

Thanks all of you for your help. I am able to take the backup of files larger than 2GB size using GNU tar utility.
