Hi!
I have a question on rsync's way to deal with files in use
or files that are modified on the source while they
are transferrred to the destination.
Yes, I searched the web and found
In rsync, transfers are done to a temporary file, which is cut over
atomically, so the transfer either happens in its entirety or not at
all. Basically, rsync does "the right thing," so you won't end up with
partially-backed-up files.
and
On the destination rsync always writes to a temporary file and then
renames it. This operation is atomic on Unix, so processes will
either see the old file or the new one. Processes that have the old
file open it will continue to use it even after it's been unlinked.
Well, but this only describes how rsync is dealing with files
on the destination directory.
But what if e.g. a large mailbox file is changed on the source directory.
Is there a checksum check after the transfer and if yes - how often is
the file
transferred again by default.
Is rsync working with a shadow copy of the source files?
I hope you can help me.
Thanks!
Homer
