Hi guys!
I’m a newby in the list.
It’s a lot of time I’m tryng to make an incremental backup of some folders of my linux machine on a nfs partition created on wdSharespace, unsuccesfully. I’ve mounted the nfs partition
I’ve tried using rsync and tar. I’ve tried with different tools:
-
custom scripts for weekly incremental backup using rsync (I attach the scripts): they make a first full backupc, and then the next day the incremental backup results void and so the third incremental backup is a full backup again.
-
using backuppc, anc mounting the nfs partition on /var/lib/backuppc with the correct owner and group (backuppc). Launching “/usr/share/backuppc/bin/BackupPC_serverMesg backup all” or accessing to the web administration page it returns the error: “Can’t connect to server. (unix connect: Connection Refused)”
-
using backkup-manager with the options: BM_REPOSITORY_USER and BM_REPOSITORY_GROUP and with the owner and group of the mounted partition set to “root” I get the error “chown: changing ownership of `/mnt/nfsWDShareSpace/BackUpManager’: Operation not permitted”.
Can you give me any suggestion. Ask me if you need more informations.
