Hi Jehan
What do you mean by

Since then, I fsck.ext3 -f the /var partition which caused me the
problems, it works fine now (last 3 days) ,

What works fine? The restore? Are you not seeing the file corruption anymore?

Yes the restore worked fine, but maybe it's not due to the fact that I run fsck, but only because since those last 3 days, nobody was manipulating the files while they were dumped !? Someone else on this list (Paul Bijnens) told me that it is most certainly due to that fact that I use dump to backup that partition , and if you read that :

http://dump.sourceforge.net/isdumpdeprecated.html
it could be a good explanation . so do you confirm that I should move to :

define dumptype root-tar {
  global
  program "GNUTAR"
  comment "root partitions dumped with tar"

Anyway, if you have other suggestion , I'll appreciate, because today my only solution is to move that backup from dump to tar . But will this solve definitly my problem, will tar create other ones ? which (tar/dump or soething else) is best finally ?

You really think there is a "universal best"?  Tar has its own problems
including increased time of backup and inability to handle some extended
types of file attributes.

Do your client OS/filesystem combos support ext3 snapshots?
Some recent ones do?  If so, you could set things up to make a
snapshot just before the amdump, use dump on that non-changing
snapshot, then delete the snapshot after the dump.

indeed that might be a good solution .
