CygwinToLinux

From RdiffBackupWiki

I am able to backup files from a laptop with win2k / cygwin to my linux server.

I am using rdiff-backup version 13.4

On the cygwin side, I encounterred a problem with daylight savings time. I got around it by forcing the timezone to UTC in my backup script.

TZ=3D

export TZ

... rdiff-backup

On the restore side, I encounterred a problem with permissions. The userids from cygwin obviously don't match my linux server. I do not like to run as root so I had to make the following change on the linux side:

[[TroelsArvin]] asks: Gregor, is uid 9 some magic UID (Administrator?) on 
Windows? What does the patch do?
