tar is unable to backup file > 2GB

[John Jayaseelan]

Hi,

tar & cpio utilities are giving following error
while trying to backup file > 2GB.

tar: file size > 2GB not dumped.

Any idea why how this can be solved.

Thanks

tar is an older UNIX utility, and has a 2GB file limit.

You can use a number of other utilities. What's available depends on your OS.

GNU tar is available for most platforms, and does not have this 2GB limitation. You can use fbackup/frecover also on many platforms.

Good luck,

Vince

He's right above.

I have attached unix binaries for "gtar", compiled for large files. See if this works.

You must have your file systems set up for "large files" to use it.

64 BIT tar on 11.11/11.0 on hp/ux has no problem. I believe that you are on a 32 bit tar, or have initiated the tar with cron that has a
2GB ulimit.

Solution put on cron patch for hp/ux and/or insure you are using 64Bit.

tar and cpio have had this problem for a long time.
If your not moving data to another platform, then 'fbackup/frecocver' is definitely a far better tool. It provides a deal of flexibility over tar and cpio. (even the GNU versions). Check out the man page
$ man fbackup
$ man frecover

Here's alink to the GNU versions which suport >2Gb
