If you increase the incremental count, that will result in more full
backups being kept. The more incrementals you keep, the more full
backups will be required to support them.
Considering that full backups do not take up much more space on your
drive than the incrementals due to pooling, I would recommend that you
not worry too much about it and just let BackupPC keep what it needs
to. After 5 days, all of your old incrementals will have been replaced
and then the old full backup will also go away. This will result in one
extra full backup being there most of the time, but the only alternative
is to delete all of your incrementals whenever you do a full backup, and
I would NOT recommend that.
