We have an SDLT drive that we'd like to use for full backups, but a small DDS2 drive for incrementals. The incrementals tend to be very small since we're a small research group, so it's a waste to do incrementals to the super large SDLT tapes.
What I have setup now is 2 configurations, 1 that does a normal amanda thing for 4 days of the week, and a forced full on the fifth day so that I can use However, since amanda attempts to run the full backup across the dumpcycle, this is going to lead to an overflow of the DDS2 drive eventually. What I am wondering is if I can fool amanda. If I tell the "incremental" config file that the dumpcycle is 5 days, and that runspercycle is 4, then do a full backup on Monday, will Tuesday through Friday not do any level 0 backups (provided there isn't a major change in the contents of the machines)? Or, should I set dumpcycle and runspercycle to some large number, like 1000 days? It seems that setting dumpcycle and runspercycle up that high will cause it to only do incrementals, but I could be confused as to how amanda is calculating what level dump to do on any given night. -- Chris Dahn, SERG Code Ninja 3141 Chestnut St. Attn: MCS Department Philadephia, PA 19104 Office: 215.895.0203 Fax: 215.895.1582 <->Software Engineering Research Group<-> Feel the SERG! http://serg.mcs.drexel.edu/ CAT 186, The Microwave http://pgp.mit.edu:11371/pks/lookup?search=Christopher+Dahn&op=index
