Topic: backup to tape failed

[miceni]

HI, I'm trying to use 4GB compaq SCSI tabe backup for SME backup, but it doesn't work. Can someone guess why doesn't it ?

here is my daily log :

Try the backup again without removing the tape. If it now works, you have a common flexbackup problem.

Charlie Brady posted a fix some time ago on the FTP site at /pub/e-smith/dev/5.6dev/updates. I tested it and it fixed the problem for me. N.B. Although it's in the 5.6 directory, I'm running 5.1.2, and it works fine for that version too.

P.S. I switched over the Christmas holidays to Shad Lords' excellent Arkeia contribution (www.lordsfam.net). Well worth a look, especially if you also install the Windows or Linux GUI front-ends.

Hi,

I'd like to try the fix, but there isn't anymore in  the /dev directory. Could you give me the name or any other location to get it ?

thanks, Miceni

Miceni,

It looks like it's in the 5.6 ISO (flexbackup-0.9.8-07es.noarch.rpm). If you haven't got that yet, let me know off-list and I'll email it to you (it's only 38k). It definitely works on < 5.6.
