Hi,
i have a little creepy Problem.
All Jobs, which take more than a day (24h), are always run as a FULL
job. Any tips or suggestions where to begin to get the problem solved?
To my knowledge Bareos decides at starttime of the job if it should be a
full, incremental or whatever so the duration of the job doesn't matter
at all. I suspect that you lack some valid previous full backup within
the retention period so you should carefully check this settings.
Ok will check the retention periods, for now i'm "building" more jobs
with less data/each. So it will better distribute along our drives too.
And last question, i need plenty of time for jobs with compression
enabled, but without it takes somethink like a 10th of the time,
should i use more the hardware tapedrive compression from LTO6 or the
bareos compression?
It depends. Bareos compression is done at the client(s) and per file. So
if you have many clients with compressable data and congested network
you should use Bareos compression to scale with the number of client
CPUs. If you have only a few clients and your network is really fast you
better let the LTO6 do its job.
Also check if you are using lz4 compression and attribute/data spooling
to get the data fast enough to the LTO drive.
the Network is for most of the Machines 10GbE.
The Data gets spooled on the Backupserver and then written on the
tapedrives. Writespeed to the tapedrives wasn't really an issue, most of
the writecycles per spooling (spooling 2TB per Drive) are Writing
>120MB/s per Tape Drive (5 Drives simultanly)
So i have used LZ4HC, but with your suggestion i have disabled
compression for now and let the lto6 compress the data.
