[flexbackup-help] Flexbackup hogging resources
|
From: Jim C. <jc...@tl...> - 2005-04-11 19:35:18

For the last few days I've been getting problems with flexbackup not =
completing backups. I'd like to say that it is just a strange =
phenomenon and has nothing to do with anything I've done but that would =
be a lie. :)
However, I am not sure what I've done to keep it from working. A couple =
of things I've done is change the type of backup from star to afio to =
dump to tar and then finally back to star. The weird thing is that afio =
and star used to work and now they don't. Additionally, whenever I try =
and do anything with flexbackup I get an "Out of Memory" error now.
Any suggestions? Thoughts? Below is a copy of the config file I use. =
I am running commands like: flexbackup -set tlb or flexbackup -newtape =
(which doesn't success either). This morning I even tried to do a -list =
with a -n and *that* didn't even finish!!
Suggestions?
TIA - Jim
