That would probably be correct.  You gave amanda a value for the 
dumpcycle, normally considered as number of days.  You also gave her 
a 'runspercycle' I assume.  If 'dumpcycle' is 7, and 'runspercycle' 
is 5, then amanda knows she has to schedule so that in 7 days, but 
only 5 runs, she must do a full on each and every entry in the 
disklist within that 7 elapsed days, with only 5 runs to do it in.
If you have a changer robot, so that amanda can use more than one 
tape, it might be helpfull when you have a makeup tuesday, to let her 
use a second tape by setting runtapes to 2 just for that tuesday run.

If you have holding disk space enough to hold the backup, read those 
portions of the docs carefully, then it could have run on monday 
normally, and you could have flushed it first thing tuesday (to the 
mondays tape it was looking for) and all would be well again.

OTOH, if you have the changer, why not just go ahead and leave the 
crontab entry alone & let her do a monday backup even if it was a 
holiday?

The acronym for amanda is Advanced Maryland Automatic Network Disk 
Archiver.  Note the Automatic.  If left to settle into a routine 
without any interference from us, amanda will, after a couple of 
dumpcycles to get things figured out, be as happy as can be.  She 
doesn't take holidays off, doesn't ask for a raise or longer coffee 
breaks, what more could one ask? :-)
