I do incremental backups using dirvish. (dirvish makes incremental backups using rsync and hardlinks).
This has worked perfectly on our old server (nothing fancy, just a linux box with one disk on
/). On our new server we have a special mount for mass-storage (SQL dumps and other things). This is an NFS-mount.
The trouble is that the content of the mount is not copied.
I run the copy as root, so I should have all the rights.This is the content as it is on the live-server:
drwxrwxrwx 5 ouruser ouruser 4096 2011-03-31 10:14 nfs
drwxr-xr-x 9 nobody nogroup 4096 2011-04-05 13:36 sql-backup
drwxrwxrwx 2 anotheruser anoutheruser 4096 2011-03-31 10:14 nfs
(and that is empty)
It's not clear at all to me why this is. Maybe it's got something to do with rights (the NFS uses a different rights system, right?), but AFAIK I should be able to read (and thus backup) the files. There is a lot of stuff on the internet about dirvish and copying TO NFS, but my target system is just a basic linux box.
