according to the tar docs, the --listed-incremental will check on the files listed in the file if the incremental file is not empty. I suppose the listed-incremental file got filled during the sendsize proceedure?!
During the sendbackup step, tar is apparently going through and checking the list, as no data is being transmitted while tar is doing this check. with a dtimeout of 30 minutes, i would get this unexpected timeout. Is this how its suppose to work for a level 0 dump? ( 4 hours (wall-time) sendsize, ~4hours (wall-time) incremental check, and finally the transfer of the data ( i suppose longer that 4 hours )) Is this how it will work with other level dumps ( with the exception of the transfer of data step) ? /gat 10690 ?
