Hello,
I've set up rdiff-backup (v. 13.4) on my (local) Win2k machine and a
(remote) Fedora Core 1 machine. Much thanks to David Kempe for his
rdiff-backup/cygwin bundle and Dean Gaudet for his unattended backup
instructions.
The backup is now *almost* working. Rdiff-backup doesn't like Win2000
dfs root directories, I think. The root directory contains "folders"
for each dfs link that redirect you to the network share associated with
that link. When rdiff-backup does the initial mirror, it works just
fine, but creates these dfs link "folders" on the remote linux system
with no permissions (ie, 000). When you run the backup again, it will
run for a while and then fail:

Now, I'm thinking the easy solution is just to not back up the root
directory, since it doesn't contain any data, anyway. So after deleting
the rdiff-backup-data directory and the remote mirror of the root
directory (/home/seth/ACG/root):
C:\rdiff-backup>rdiff-backup.bat --force --exclude c:\dfs\root c:\dfs
seth < at > remote::/home/seth/ACG
Which puts this on the command line:
C:\rdiff-backup>python2.3.exe -S c:\rdiff-backup\rdiff-backup
--remote-schema 'plink -C -i backupkey.PPK %s rdiff-backup --server'
--force --exclude c:\dfs\root c:\dfs seth < at > remote::/home/seth/ACG
Which works just great, except it *doesn't* exclude the c:\dfs\root
directory, so any further use of rdiff-backup:
C:\rdiff-backup>rdiff-backup.bat --exclude c:\dfs\root c:\dfs
seth < at > remote::/home/seth/ACG
Results in the traceback above. So, I think I'm using the --exlude
correctly; I want everything in c:\dfs except for c:\dfs\root. Am I
screwing that up? Does Cygwin introduce some complication?
