Given my results with one particular file system I
don't think I understand dump/run/tape cycle.
My configuration (2.4.2) has these settings:
dumpcycle 1 weeks
runspercycle 6
tapecycle 18 tapes
Does this mean that given a level 0 today, the
next level 0 will be at the latest 1 week from
today? For most of my file systems that is
what I'm seeing.
Or could it mean that within each dump cycle
there will be at least 1 level 0 but that
they could be up to 12 dumps apart (begin
of one cycle, end of next)? That is nearly
what one file system is doing.
Here is the amoverview for the strange fs.
date 11 11 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12
host disk 29 30 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19
butch /w 0 1 1 1 1 2 2 2 2 0 1 1 1 1 1 1 1 0
<-- 10 days, 9 dumps apart --> <-- 10 days, 8 dumps apart -->
Is this normal, nothing to be concerned about?
For the other 7 file systems, the intervals between
level 0 dumps were only 2 to 5 dumps (the latter only twice).
All from the same host, the tapehost, so availability was
not a problem. Plenty of holding space and tape capacity.
Comments?
