Hi,

After 10 days from marked volume as Used of Full, volume will be ready 
to recycle process. If Bacula will request this volume then volume will 
be recycled, all backups on this volume will be lost and volume will be 
writing as new volume.

In your configuration of Pool resource volumes status rather will be 
Used (because of "Use Volume Once = yes"). 'Recycle Current Volume' 
directive will be try to run recycle process on current using volume. 
So, you should guarantee that current volume is ready to recycle (older 
than 10 days after marked volume as Used) eg. by using fixed volumes 
numer in pool.

Number of volumes in pool you can calculate by using below schema:

                           Vol. Retention time
volumes number = --------------------------------------------------   1
                  number of backups per volume * backup interval time

In your case that may be:

                    10
volumes number = --------   1
                   1 * 1

so number of volumes on pool should be at least 11.

Please note that 'Use Volume Once' directive is deprecated and its 
actual equivalent is:

Maximum Volume Jobs = 1

Answering on your question:

"after 10 days bacula remove old backup's in this pool?"

No. Volume Retention is connected with volumes so I suggest to treating 
this on volumes level.

Regards.
