Hello. Lately I have been getting more and more worried about data on my FreeBSD box at home. I am forming a "real" small-scale backup policy with two different big USB harddrives (yet to buy) storing regular incremental backups (yet to figure out). The idea is to have those harddrives mirror each other for extra security.
Handbook reads dump(8) is the best backup program there is. So I am giving it a try - only to find out that I don't understand at all the meaning of that modified Tower of Hanoi algorithm descibed in the manual page and elsewhere. The manual page says it is "an efficient method of staggering incremental dumps to minimize the number of tapes." I just don't get the picture here. So, could somebody please give an idiot-proof explanation why "3 2 5 4 7 6 9 8 9 9" is such a tape-number-minimizing dump level sequence (with helpful examples, if at all possible)? How does it work? Am I relatively safe doing level 0 dump every two months and increasing dump level for weekly backups like the following, given two separate harddrives storing them? Date Dump level 2005-09-01 0 2005-09-08 1 2005-09-15 2 ... 2005-10-27 8 2005-11-03 0 Thanks.
