fbackup command question

[Grant Willey]

Hello,
Is it possible for the fbackup command to do "bit level" verification? I am evaluation Cactus software's Lone-Tar product which touts "bit level" verification - certainly much better than fbackup I think?? Can anyone help? Thanks!

A backup is only as good as the data being backed up and the media to which it's being copied to. If you have crappy media then your backup will be questionable. If you back up files while there is Io occuring to them. then your backup is questionable. If the hardware doing the writing of the data to the media is questionable then so is your backup.

NO backup software can GUARANTEE that you will be able to RECOVER data from a backup. Sure, they can say they can, but in fact they can't! If enough error occur on the media AFTER it's been removed from the tape drive, then it's up to fate.

If you really need that level of protection, then you really need to spend millions and get yourself enough DISK to perform disk to disk backups in a raid'ed disk array.

A disk to disk copy is about the way of some sort of guarantee. A tape backup is useful to have, but it is not the be all and end all.

We have just implemented an SRDF (EMC) solution between two sites, where our production disks are copied to DR disks. This actually works quite well and we have tested and brought up our databases on a different server. Costly yes, but peace of mind. We also use tape backups, peace of mind no, but easy to recover things. It all comes down to how much money your business is prepared to pay for a DR solution.

I agree with life free or die and the fact that you need to spend a lot on disk to try and garantie restore, just one point you need tape backup to help increase you chance to restore the data after some unwanted data deletation, and well it help sleep at night.
I have no knowledge of Lone Tar but it sounds like a lone quest

I believe you guys are missing the point. I simply want to know the following: Can fbackup do bit-level verification or not? Or are there any Unix commands that will? I don't need explanations of how to configure my systems, just an answer to the question. Thanks for your time and responses.
