Re: [Bacula-users] Mark files/directories take 28hours

[Kern Sibbald]

Hello, The byte size of your files for restore is immaterial.  What affects the time to mark files is: 1. The version of Bacula you are running.  Very old versions are very slow. 2. The number of files in the fileset. 3. How much memory you have. 4. How well you have tuned your database. The last two items are the most important.  With the fileset size you have, you probably need professional help, though suggestions on this list are always excellent.

Not sure why took so long. Is it possible to do some tuning? I could see there is a process "bacula-dir" which occupied 4GB memory only. While postgres processes are below 2GB memory. There are 7.7GB is free and 3.5GB for cache.
