This is very appealing and timely. Other than somehow flagging when packs have been done on the source database it would seem to be quite usable. Have you done tests to see what happens when an -- append is run when the content has changed earlier in the file than the destinations end? Is the keeping of that inline left up to the driver?


I haven't tested anything except the basic operation of this.
If, between two runs of rsync3 with --append, the database is packed and subsequently grows larger than it was on the last run of rsync3, I think the --append would produce a bad backup file. If you run it with --append at high frequency, the probability of this is situation is low,
but not zero.
That's where the extra time spent by --append-verify would be justified.

I suppose you could also run an rsync on the log and run rsync with -- append-verify
when you see new Pack log messages.
