could not tar any file more than 8G large to tape 1

[mm8294]

I need to do a cold backup of our Oracle Application instance to tape every night. It worked well until this weekend. What I did is:
1. shutdown the instance.
2. tar -cf /data/backup/oracle_bak.tar /oracle_base/*
3. compress oracle_bak.tar
4. tar -cf /dev/rmt/0c /data/backup/*

Before last week, the generated .Z file is 7.5G and there was no problem. But the database is growing and last weekend, the generated .Z file is 8.5G and I cannot tar it to the tape. No error message was given. Is there any OS limit of the tar command? This is emergency because if I can not tar it to tape, then I have to remove it from the disk to save space for another backup! Any suggestion is appreciated.

Thank you very much.

The file size field in a tar header limits the max file size to 8gb. You can download/install gnutar. This will allow you to go over 8gb.

Thanks a lot, tuka. Could you tell me the website to download it? Thanks.

http://www.gnu.org

is the web site. I am using version 1.12 but
I think the latest is 1.13

Thank you tuka. Is the name of this package gnutar or tar? Actually, I searched that website before I asked you for help but found nothing related to gnutar. However, I found tar 1.12 .

Thanks.

tar 1.12 is the one. My mistake in that I prefaced tar with
gnu.

I am using tar 1.13 NOT 1.12.
