Topic: Friday backup - always wrong

[Gaetan]

Hi,

I have set up E-Smith so a backup is done every day of the week at 2h00 am.
Monday, Tuesday, Wednesday, Thursday night backups are well ok BUT when it comes to Friday one, it never works.
I have changed the Friday backup tape thinking that the tape could be the problem. I still have the same problem. Here is the log:

flexbackup version 0.9.8 /etc/flexbackup.conf syntax OK

Can someone tell me what to do ?

Looks like a bad tape.

[Des Dougan]

The problem is a bug, as yet unresolved, which I reported a while ago. You will note that the tape is at block 0. If you run the backup again, without taking the tape out, it will work. That said, you also noted it ran OK on the other days of the week. Do you leave the tape in the drive and only change it on Fridays?

I actually leave the tape in the drive ... The backup is programmed to start on Friday night (Saturday morning at 02H00 am) ... Then the tape stays in the drive until I come back in the office on Monday morning .... Which means that the backup is also done (on the same tape) Sunday AM and Monday AM.
Even then, the backup does NOT work.

Hope this is clear ....
