Hi,

I'm still using bacula 1.38.5.

To prevent shoe shining (writing, rewinding, writing again) with a tape
drive bacula uses spooling.

When using spooling, the data is first spooled to local disk file, then
it is written to tape (despooling).  When there is more data to backup
then the maximum spool file size, this process is repeated as many times
as needed.

The spooling to the file and the writing to tape is not concurrent.  Is
there a reason for this?  Has this changed in later versions?  Are there
any changes to be expected in this?

I'm asking this because backups without spooling are faster than those
with spooling.  Is this normal?

Best regards,

marc
