Hello again!
Whilst setting up a full dump configuration to do monthly full dumps
to tape, I'm torn between either:
strategy "noinc"
or
dumpcycle 0
To do a full dump. What's the difference here? Does it matter which
one I use?
Heres my reading of what I've experienced from experimenting with these;
Suppose that a filesystem has grown too large to fit on the tape.
noinc will simply not dump that filesystem at all on that run.
dumpcycle 0 will fall back to incremental for that filesystem.
so when will amanda do a level 0 for that DLE, if that result for
dumpcycle 0 would be true ? in normal cases, amanda would simply say
"dumps too large" or something like that.
This is where amanda starts 'optimising' which tape it wants next based
on when it last did a full dump and when the incrementals happened.
If I understand it right, it would try to schedule the zero-level for
the next run. If again it couldn't fit, it would fall back some more.
I was just mentioning this because having a backup completely *fail*
when using noinc can be very unfortunate
:-/
which amanda version do we speak about ?
its debian sarge, and dpkg -s tells me;
2.4.4p3-2
...i'm just testing the spanning patch. this would be another testcase.
so, thanks's for your hint :-)
