Hello everyone,
I recognize that this isn't really related to Amanda, but I thought
I'd see if anyone has a good trick...
A number of DLEs in my Amanda configuration have a huge number of
small files (sometimes hardlinks and symlinks, sometimes just copies)
- often times in the millions. Of course this is a class corner case and
these DLEs can take a very long time to backup/restore.
Currently, they are mostly using dump (which will usually report
1-3MiB/s throughput). Is there a possible performance advantage to using
tar instead?
On some of our installations I have bumped up the data timeouts. I've
got one as high as 5400 seconds. I suspect a reasonable maximum is
very installation dependant, but if anyone has thoughts, I'd love to
hear them.
Thanks for any ideas!
