Hi all,
My orginal question was:
I have a DAT TLZ07 tape drive, I am using DAT cassettes 120M and 90M
long.
My backup procedure use the command
/sbin/vdump-u${level}f - $curr_fs | dd of=/dev/rmt0h obs=512k
The $level is 4 for incremental backup, or 0 for full backup.
The $curr_fs is the file system to backup.
My question is : What is the maximum size of data I can backup on level
4 and level 0 with this kind of hardware using this command.
Thanks to all who responed quickly:
Paul Casteels casteels_at_uia.ua.ac.be
Alan Rollow alan_at_nabeth.cxo.dec.com
Jim Wasden wasden_at_swvs40.orl.lmco.com
Add to this question, I attached the backup log file and I manage to
backup up to 15Gbyte on single tape.The system is Alphaserver 2000 and
most of the file are text files.
