No... as a matter of fact I use quite the same batch file to perform the backup from long time ago... Now that you mention it, I went to check out "-Limbo" in the help, and I see that I misunderstood the meaning of that switch. I'll remove it, of course!

I thought that using "-r" makes gbak to overwrite the destination file if already exists. Am I wrong?

> why do you specify -n option?

Well... I'm not sure now, but I think I had a problem once restoring a database with some problems of validations. Again: I will remove it now...

> why do you each time set -p 4096 ?

I always use a page lenght of 4096...

> Have you read anything about gbak options?

Well... I did... but (now I'm quite ashamed!) to tell you the truth, probably I didn't invest the proper time to learn everything about it.

Do you think that any of my mistakes is causing that behavior?

Thanks a million!
