[Bacula-users] volume/file size and speed
2010-05-11 10:47:34
I'm currently set up with a File based backup system (no tapes). Initially I
wanted to make 1TB files, but learned (and read) that recovery of a backup is
very slow with large files. So, I reconfigured it to create 1GB files. This
will create significantly more files (1000x) but this won't be a problem for
me. My questions:
1) when I created the volume set, it pads the file with 0's. So, file 1 is
0001. What will happen when I get past 9999?
2) I ran a backup last night, which created 475 files. I notice when trying to
perform a recover, it is still slow. I suspect this is because it's spinning
through all 475 files. Is there a way (via bat or bconsole) to recover faster?
If I were given an option in the recover screens (ie: what specifically do you
want to recover), it wouldn't need to spin through all 475 files to build a
directory tree.
3) If I use bconsole I can specify a single file to recover and it is VERY
fast. But there doesn't seem to be a way to specify an entire directory. Or
am I not looking in the right place?
Thanks!
