pragmatics of holding-disk space
2005-07-06 18:55:00
Greetings. We've had some problems with the amanda backups on our one
Solaris system. We're still tweaking, so I won't yet go into details,
but I did want to ask a question.
We're trying to backup some relatively large file systems to an SDLT 320
tape drive. Currently the largest file system has about 60 GB of data,
but the trend is upward, of course.
My question relates to the detailed handling of the holding-disk space.
We're trying now to use a holding disk of 3 GB, with a chunksize of 1
GB. Does this make sense? I.e., these are mostly local file systems,
so amanda is going to be shoveling data pretty quickly into the
holding-disk area. There are 60 of our chunks in the large file system,
while our holding disk can hold only 3 of our chunks. Is it possible
that amanda would put chunks into the holding disk faster than they can
be removed to the tape drive (and, hence, conclude that there was no
more holding-disk space)?
Thanks.
- Mike
