flush questions
2009-02-18 12:35:44
I am considering moving to Amanda 2.6.x to try and get better tape
usage.
The following was found in the zmanda documentation.
"During amdump run, flush-threshold-scheduled and flush-threshold-dumped
determine if the taper can start writing to a new tape. At the end of a
run, taperflush is used to determine if the taper can start writing to
anew tape.
flush-threshold-dumped 100
flush-threshold-scheduled 100
taperflush 100
autoflush yes"
With the above settings lets say that my holding disk will hold 1 tapes
worth of data and my backup is 2.5 tapes.
Tape writing start when the holding disk is 100% full. Correct?
I do not understand how the flush-threshold-scheduled parameter is used
in the calculation. Can someone explain the use of this parameter?
At the end of the backup what happens to the .5 amount of data left on
the holding disk? In this case does it wait until the next backup when
the holding space gets to be 100% full; 50% from the leftover and 50%
from the new run or does the autoflush force the flush before anything
else happens?
Thanks
Robert
