Bacula does not automatically recycle a Volume. It attempts to keep the
Volume data intact as long as possible before over writing the Volume.
- The default Volume retention period is 365 days. Note, this directive
- sets the default value for each Volume entry in the Catalog when the

- changed for each Volume using the Console program.
By defining multiple Pools with different Volume Retention periods, you
may effectively have a set of tapes that is recycled weekly, another

- send a heartbeat signal to the File daemon. The default interval is
- zero which disables the heartbeat. This feature is particularly useful
- if you have a router such as 3Com that does not follow Internet
- standards and times out an valid connection after a short duration
- despite the fact that keepalive is set. This usually results
- in a broken pipe error message.
