Backup Central

hello all,

please, i need some help, maybe someone can point me to the right solution:

i have no success in backing up to a windows machine using a mounted share.

first i tried using rdiff-backup V0.12.7 in --windows-mode which works but
quotes all Capital-letters which leads to a working but unuseable backup
because many filenames are in Capital letters.

with V0.12.8 the same problem exists

with V0.13.6 option --windows-mode is no more availiable, and
when i try to do a backup i just get following error message:

[root < at > server src]# rdiff-backup --force -b /backups/Dir/ /mnt/backup/test

I don't think its going to work.
we need to do some serious patching to the detection code to make this work.
probably even change the date format of the files.
you can probably rdiff-backup to a tmp directory, tar up the repository,
then dump it on a windows share...

i wonder what it's trying to fsync... i suppose we could ignore an error
there, but you'd probably run into more problems.

you could try this completely untested patch.

I thought fsync didn't work on windows file systems at all. - this means
smbfs, cifs and cygwin.
I think your patch might help, but I would like to eventually see
rdiff-backup have full support for writing to windows filesystem. I am
not sure what is involved fully, but one day I will get one of my guys
to take a look.

hello,

thanks alot for your help!

because the backup is not "the thing to play with" we decided to setup another
linux machine to backup on it.
there are just too many advantages: efficency, ext3, no quoting etc.etc.

i never had problems using rdiff-backup between linux boxes so far as they
used the rdiff-backup version it usually works just great !

ng,
robert
