[flexbackup-help] flexbackup on tape

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

Dear flexbackup user's

=20

I try to user flexbackup since 3 weeks, and for the moment the result arent
so good.

My problem is the next one.

When I made new index with -newtape, it takes more than half an hour to make
it.

My tape is 4 Go storage (so quietly small) and my flexbackup.conf is the ne=
xt
one.

And another is anyboy can help me to define exactly what the bocksize is and
how to configure it .

Thanks for all

# 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

# 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'} =3D "/home /usr";

#  $set{'set2'} =3D "/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.
