Hi,
do you know a way/tool to save the directory layout that was
synchronized to a file?
So you later know there was a file "foobar" that was copied from
the source to dest, and another file foobarcommon that existed in
both. And know the size/mtime/hash of both.
There is the log-file option, but it does not seem to be machine
readable. Especially files that have line breaks in their name
completely mess up the log.
And the log-file uses MD5, which is outdated nowadays. Something
like SHA-2 or newer would be more appropriate.
And I would like to know the entire directory layout, not just the
changes in the log. So when you delete a file, it can check, the
file was there during the previous synchronization, but now it is
gone, so delete that file in the destination. This is different to
a non-existing file, a file that does not exist now and did not
exist previously, would not need to be deleted.
Or when there a file X with a hash was deleted, but there is a new
file Y in the source and a file X in the destination that all have
the same hash, it is likely that we do not need to copy Y, and can
just rename X in the destination directory. At least with a strong
hash like SHA-2
Since rsync knows which files are in a directory when it is
syncing it, it has all the necessary information, so how can they
be accessed and remembered?
I know about unison, but it solves a different problem, since it
ties a source-destination together, rather than storing changes in
one directory.
Best,
Benito
