Hallo, David,
If nothing has changed it needs no additional space.
That's not quite true. It doesn't need any extra space for files,
but it will still need space for directories.
Ok - may be some kilobytes ...

At minimum one block per directory. Picking one of my backups at
semi-random, that's 94829 directories, many of which are very big so may
take hundreds of blocks each.

And this is just my personal backups. At work, my home directory
contains ten times as many directories, and we can assume that each of
the dozen people I work with have something similar, for of the order of
100 times as many directories. It doesn't take long for all the
directories to start being measured in gigabytes.

Corrupting rotation may still happen during the rotation phase, when 'cp -al' is being executed. And this is much harder to track. I had to create a wraper script for rsnapshot, which checks if the previous backup session has actually completed and if not it moves hourly.0 out of rotation.--

It doesn't know how much space it will use.


Right. But the beauty of sync_first is that the sync call
in a sense acts as such a check, too: if it runs out of
space it fails before any corrupting rotation has occurred.

That sounds great! Would you care to share it? :-)

Here it is
http://pastebin.com/fYUbyhmk

It is intended to be used with hourly rotation (lowest interval which executes 'cp -al')--
