Time machine backup question....
Hello - hope you can help
I have two ReadyNAS Duos, both on the latest version. One is primary and the other secondary with backups from one to the other using Rsync over a simple LAN, and all is good.
The primary is also set up for timemachine backups from a MacBook Pro, and again, all is good but I also want to set backups of the time machine form the primary Duo to the secondary and have a few questions.
- I believe that the timemachine backup has to be a push, that is, from the primary to the secondary, a pull from the secondary device not currently being an option. Is that correct?
- Also, on the primary device, the destination needs to state ‘c/.timemachine’. Is that correct?
- Does the secondary Duo have to have timemachine enabled for that to work?
- Other than the first backup, is the timemachine backup an incremental, or will it be a full back up every time? A full back up every time would be a problem….
- Does a particular Id and/or password need to be used? I ask as I’ve never managed to make a successful test connection
- Anything else that I need to be aware of for it to work?
I'm stating 'Time Machine' as the source, and for the destination ...'Remote: Windows/NAS (Timestamp)', the target host name and a Path of 'c/.timemachine'
On the other hand, am I over thinking it all & all I need do is select 'Time Machine' as the source on the primary box and use NFS for an initial copy to a newly created directory on the secondary box, then change that to rsync like any other backup?
Many thanks

- Enable Time Machine on the backup NAS setting the same quota as on the primary NAS then disable it again.
Setup a backup job on the primary NAS choosing "Time Machine" as the source and a new share on the backup NAS as the destination. Use NFS then change to using Rsync.
The Windows/NAS Timestamp should only be used for NAS to NAS backups if one of the NAS units supports neither NFS nor Rsync. CIFS is not a native Linux protocol. - Great thanks - I was clearly over-thining it. The first backup is going to take a while so I'll set it running while I'm away next week.
Thanks for your help! - One more thing: of course you should backup the Time Machine share whilst not running a Time Machine backup.
