It is the _maximum_ time distance, between two full dumps of any filesystem.
However Amanda tries to spread level0 dumps evenly across the
typecycle and to balance the amount of backups on each tape.
The result is a mix of full and incremental dumps on each run.

a run means a call to amdump.

Every entry in the disklist is handled separately.

Currently you loose :-(. All filesystems larger then one single
tape will fail.
This is an open project, looking for developers. If you'd like to
help, please take a look at the Amanda Ongoing Projects Page, where
more up-to-date information is likely to be found about this project.
The current work-around is to use GNU tar to back up subdirectories
of the huge filesystem separately.

yes, (but if you have a large holding disk, you can
use amflush to flush several runs on one tape)

if you put amcheck in your crontab, you will receive mail
prompting for a new tape.
