Hello,
for the benefit of all here are some bacula drawbacks I stumbled
upon, and how to work around them.
1. If you want to run a bacula server on FreeBSD use at least 6.3
STABLE (RELEASE may work, untested). On earlier releases bacula
using multiple concurrent jobs will hang randomly under high load.
This is due to a bug in FreeBSDs libpthread.
2. If restoring "long paths" (ie paths longer than 260 chars) to
a windows box use an 2.4.2 fd. The 2.2.8 windows fd handles
long filenames well, but the windows box may bluescreen mid
restore. This didn't happen with 2.4.2.
3. If using VSS be aware that you can't run multiple concurrent
jobs on the same client, since multiple VSS jobs, even if
referring to a different drive (ie c:/ and d:/), block each other.
4. If you want to compile bacula with newer SunStudio 12 compilers,
you have to workaround a bug in newer CC patch versions: remove
all volatile bitfields in src/lib/bsock.h. (Patch attached)
There are certainly some more I already forgot about.
