NAS filesystem that supports hard links

[Tony Arnold]

Ben,

I use a Synology NAS box and has a similar problem using Backintime, which uses hard links. I tried NFS mounts, but the hard links became copies, so filled up the disks pretty quickly.

The solution was to use SSH, which is an option in Backintime (I think it required sshfs to be installed on the client). I'm doing this from Linux, not a Mac, so I don't know what your options are.

Hope this helps.

regards,
Tony.

Think connecting to the NAS via AFS may be the solution but cant find any info on doing it from linux to this specific NAS.  doing it with NFS was tricky enough.

For a year or so I have been using a d-link sharestation NAS in RAID0 for backups of a ownCloud server.  I've been using duplicity but now due to the size of the backup this is proving unpractical (I have to take ownCloud offline once a week to do a full backup and it is taking over 8 hours).

I am moving over to a solution that used rsync and hard links but I don't think I can use this NAS, or indeed any NAS.  Originally I used duplicity as I did not think the NAS supported hard links but it says it does support MAC TimeMachine so I am thinking maybe it does.  Certainly using rsync with --link-dest to do a TimeMachine type backup it works but this does not work on the NAS (using NFS).  Am wondering if there is a way to get it working with this NAS, or a alternative make/model?  It also supports Samba.

I know there is something you can use on samba servers called Unix Extension which I think may allow this.
