Re: [noreply@sourceforge.net: [ rsyncrypto-Bugs-1897596 ] Feature request: write list of changed files.]

[David V. <dav...@gm...>]

I agree with Robin on this.
The solution I use so far is running rsyncrypto by a php script.
I control the file list to encrypt with the php script and I encrypt the
files one at a time by calling rsyncrypto in a loop and giving it only one
file to encrypt.
Using this method I know exactly was is going on and it is possible to build
a list of encrypted files within the same loop.

One other important reason why I use this method is that, at one point (I
really don't know if it is fixed yet) rsyncrypto would just stop if
something was wrong with a file while working on a directory, instead of
just outputing an error and continuing. So because of only one file I could
loose an entire backup.

Now if something goes wrong with rsyncrypto while working on one file, my
php script outputs the error and continues with the next file.

But this is, of course, just a workaround, a php script working this way
will never be as fast as rsyncrypto, especialy when dealing with thousands
of files.

By the way Robin : The last version of rsync (3.x.x) eliminates the need of
waiting so long while analysing the remote directory.

Shachar thank again for this great tool.
