I am a recent newcomer to Bacula and have bumped into a number of
limitations.
current backing up 700GiB of online storage
What type of files? Lots of small files or medium large files?
So far I have added only 2 servers to be backed up with Bacula. About 500GB
with 6 million files.
One problem I encountered so far is that restoring from a full backup can
require very large amounts of RAM. To get a list of files on bconsole from a
3.2 million full backup bacula-dir grew up to 1.2GB of RAM and took an hour
plus. Soon I will have better machines, to split the DB, SD and Dir daemons,
but I believe with better design the restore process could be faster and use
considerably less memory (ie load directories first, then as the user does
cd into a directory load the list of files).
3) Flexibility
Although Bacula is fairly flexible it can use some improvement. Specially in
the restore area. For instance it would be great to have a point in time
restore. So far the closest I have found is to restore files before a
particular time, but that may restore files which were deleted as you
pointed out.
3) Config files are needlessly over complex.
Partially agree.
I think configuration could definitely improve, but don't think they are
necessarily overcomplex. I guess this may be my view because of having used
ADSM (later called Tivoly Storage manager), which had very simmilar concepts
and configuration.
Almost every time a complex change was made to the config required
stopping everything, wiping the database, wiping labels and restarting.
Agree on that too. There needs to be a better way to start a new backup
strategy while not having to delete previous data.
as simple as leaving the level off of a Schedule run = line will cause the
director to silently crash.
Unfortunately agree. Have found processes die silently under several
circustances. I plan to monitor the processes to get alerts if they are not
running.
6) Does not track deletions between full backups. Restoration will
uncover deleted files.
I think if they implemented a good point in time restore that this would go
away.
In general I have found disk based operations to be slow compared to other
backup systems I have used. Specially considering we are currently only
going to disks.
Also if you need to restore files from a directory right now your only
choice is to restore the whole directory. One can not get a listing of all
the files and then mark them. So, your choice is to spend a long time to get
full listing or you can restore a whole directory someplace else and then
just get the files you need.
