beyond 100% thro.backup command.Then I aborted backup.

hi,
are you sure you need use complex backup by inode and
not a simple backup my name ?

cd /data_01
find . | backup -ivf /dev/rmt0

using this, you can leave jfs mounted, restore files
( or part ) under onother directoery, ecc

bye

I would log what is being backed up and then look at the log file and see what it is doing when it reaches 100%+. See if it is stuck on 1 file or if it is moving on. See if it may be a particular filesystem.

Looking at what you have would be like trying to determine the brand of milk in the refrigerator by just looking at a plastic jug without a label. You won't be able to determine anything; just like your output.

Is the stuff you are backing up compressed, if so you may see the above. The hardware compression can make software compressed files large hence you display above.

Aren't the files change during backup? Files arising during backup may not abuse the process as they are not backed up - in theory at least.

Well, can't it be an AIX bug?
