Hi,
I am a bit confused about the handling of file sizes while using
"Storage Type = File" for the sd.
The following two options are clear, they limit the size of the volumes,
if they are not limited by the hardware.
1. A record in the Storage daemon"s Device resource
"Maximum Volume Size"
2. A record in the Director"s Pool resource
"Maximum Volume Bytes" (so much for consistency)
Then I found this in the documentation:
Maximum File Size = size
No more than size bytes will be written into a given logical file on
the volume. Once this size is reached, an end of file mark is written on
the volume and subsequent data are written into the next file. Breaking
long sequences of data blocks with file marks permits quicker
positioning to the start of a given stream of data and can improve
recovery from read errors on the volume. The default is one Gigabyte.
According to this entry in the documentation I would expect bacula to
split a Volume limited by "Maximum Volume Bytes" in size into physical
files limited by "Maximum File Size" on my harddisc.
While testing the backup-system I changed this parameter without any
visible effect. I have created new volumes after changing the parameter,
to make the change effective.
Can someone enlighten me about this?
Regards Daniel
P.S. the bacula-version in question is 1.38.9-1
