Hello Shon,
Bacula reserves a drive/volume for backup when the job starts. If you have
a lot of jobs starting at the same time, they will be distributed among all
the devices/volumes available. If a lot of "huge" jobs are distributed to
one drive X while others drives receive smaller ones, it may occur that
jobs distributed for the drive X will be waiting for other jobs to finish
even if there are other available devices/volumes.
There is a few situations that a job can hang waiting for something. And
this will not depends only on maximum concurrent jobs directive.
Best regards,
Ana

Mobile security can be enabling, not merely restricting. Employees who
bring their own devices (BYOD) to work are irked by the imposition of MDM
restrictions. Mobile Device Manager Plus allows you to control only the
apps on BYO-devices by containerizing them, leaving personal data untouched!
