Paul If you can't beat the limit, use the tar options for a multivolume archive. It took me a long time to figure out that in additionn to these options, you can specify the --file option multipe times to tell tar which multiple file manes to use for the pieces of the tarfile. And the multivolume option does *not* allow you to compress while tarring. Here's a command I use to back up a WIndows C partition: tar --one-file-system --multi-volume --tape-length=200 -c --file=/offsite/lovesong/win_c-1.tar --file=/offsite/lovesong/win_c-2.tar --file=/offsite/lovesong/win_c-3.tar --file=/offsite/lovesong/win_c-4.tar --file=/offsite/lovesong/win_c-5.tar /mnt/win_c -- hendrik -- If thou thinkest twice, before thou speakest once, thou wilt speak twice the better for it. -William Penn http://nlpagan.net - Linux by Mandrake - Sylpheed by Hiro Want to buy your Pack or Services from MandrakeSoft?

In reply to Benjamin's mail, d.d. Sun, 9 Mar 2003 04:03:45 +0100: [...] file size (blocks, -f) 10 That means the system won't allow you to write files bigger than 100.000KB. One obvious way to change it is to use ulimit itself, although non-root users are limited in the ways changing the limits. From the top of my head, I am not sure where to change the system wide defaults. /etc/security/limits.conf might be one place to look at. Hi Benjamin and Hendrik, Ulimit -a shows exactly what you predicted. Thank you for the tip. I have already figured out how to go about the problem, namely by making several files, somewhat along the line of what Hendrik said. So thanks to you both! Paul -- I have the simplest tastes. I am always satisfied with the best. -Oscar Wilde http://nlpagan.net - Linux by Mandrake - Sylpheed by Hiro Want to buy your Pack or Services from MandrakeSoft? Go to http://www.mandrakestore.com

Looks like you are hitting an imposed file size limit.
