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?
