This is a corollary question to How to verify that rsync copied the device correctly when copy-devices is enabled?
When reattempting a transfer (using the
--copy-devices) flag and two levels of verbosity
-vv, I got this output:
sudo rsync -vvz --partial --progress --copy-devices /dev/sdb me@otherserver:/backupdisks/mydisk.img delta-transmission enabled sdb 320,071,851,520 100% 63.47MB/s 1:20:09 (xfr#1, to-chk=0/1) total: matches=2441955 hash_hits=2441955 false_alarms=204015955 data=0 sent 188 bytes received 21,979,001 bytes 2,837.31 bytes/sec total size is 0 speedup is 0.00
What do the "matches", "hash_hits", and "false_alarms" values mean, and does "data=0" mean?
Has the transfer been successful or not?
