tar > 2GB file

[LHradowy]

I have a HPUX 11.0, that hold a database on it. I want to tar and compress
the backup and send it to a offline backup storage. I get an error...
tar: Size of mydb/db4/hist_01.dbf > 2GB. Not dumped.

This is because of the tar I am using? Or the OS that I am using?
Will getting GNUtar fix this problem?

Thanks

From the tar manpage

Because of industry standards and interoperability goals, tar does not
support the archival of files larger than 2GB or files that have
user/group IDs greater than 60K. Files with user/group IDs greater
than 60K are archived and restored under the user/group ID of the
current process.

Guess it is the tar your using. I've heard that GNUtar does not have this
limitation. You should be able to get GNUtar from hpux.connect.org.uk or
one of the mirrors.

I'm the kind of sad, old fashioned, Unix admin who never allows Oracle
data files to exceed 2GB (actually I usually use 1GB, which was an old
Oracle recommendation IIRC). Old habits die hard! Not sure I should
recommend this luddite approach but it has served me well, and avoids a
lot of stupid grief with 2GB file limits on back-ups, NFS, file systems
etc. For as long as you name them simply, it is as easy to do something
to files named 1,2,3,4, as it is to one large file, and even easier to
rearrange files to spread I/O over disks and the like.

You're getting plenty of advice that maybe you are pushing HP tar a
little hard, yes I think GNU tar or star may be good alternatives for
you, you should also consider HP-UX 'fbackup' depending on your
archiving needs, it probably has more "exposure" on HP-UX, and is
particularly good for backup to tape.

Whilst I don't like proprietary solutions you may find it fits your
needs better, especially if you can be confident you are only restoring
to HP-UX systems.

I think most "tars" now know to exclude the tar archive being created
(GNU and star do), although I'm not logging into the nearest HP-UX box
to find out if HP's does.

The 2Gb question is more than adequately answered before - www.deja.com
is your friend.

I figured out the problem, the problem had "nolargefiles" associated with
it. Tar works file with gzip.
Thanks for all the help...
