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And the log-file uses MD5, which is outdated nowadays.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
