[rdiff-backup-users] Windows rdiff-backup-data path too long

[Wilson Waters]

Hi all,

I'm hitting a few issues with long paths in windows. I understand 
windows has issues with paths longer than 260 characters which is 
annoying... but we can deal with that. My problem seems to be with the 
rdiff-backup-data folder where files quite easily hit the 260 character 
limit when including the various rdiff-backup timestamps/metadata in the 
file name.

I get UpdateErrors indicating there is no such file or directory in the 
increments folder, generally followed by an Exception indicating a 
directory is not empty (see the full error message below)

This is how to reproduce it
1) create path/file with 190 characters.
2) perform a backup
3) modify the file with 190 characters
4) perform the backup
5) watch the error.

Searching the mailing list, it seems similar errors have occurred in the 
past

Any hints on how to get around this? Or at the very least is there a way 
to get better error messages to indicate the actual problem?
