[flexbackup-help] Looping Problem

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Has anyone experienced a looping problem in flexbackup?  I have no idea
where it's looping other than it seems to finish the backups in the .conf
file but then doesn't quit.  It starts to eat up memory and then system
starts killing processes.  Eventually it gets to a point where you can't
even logon to the machine and you have to power down and reboot.

I am running Redhat 8.0 on a Pentium III machine.  I have included my .conf
file and the commands I am using in cron.  Any help would be appreciated.

# General configuration section

# Archive type?  afio, dump, tar, cpio, star, pax, zip, lha, ar, shar

# 'copy' or 'rsync' are extra options if running in archive-to-disk mode.

# 'filelist' dumps a list of files in your cwd - for debugging
setup/exclusion

$type = 'cpio';

# Configure backup "sets".

# Not needed if you use "-dir <dir>" to backup one tree at a time.

# Each set is a simple space-separated list of filesystems

# Remote filesystems should denoted as 'host:dir'

# You can use anything (other than 'all') as set names

#

# Example:

#  $set{'set1'} = "/home /usr";

#  $set{'set2'} = "/dir3 machine2:/dir4 machine3:/dir5";

#

# "-set all" will back up all defined sets. If you are doing a full backup

# using tapes, each "set" will go onto a different tape and you will be

# prompted for tape change in between.

#

# Example: If GNU tar is called "gtar" on your system:

# Example: use "mt status" instead of "mt tell"
