RN104 Replication to 2nd unit
Hi all,
I have a ReadyNAS104 in my house and it currently backs up to a 3Tb USB drive each week. I am now wanting to buy a 2nd RN104 and put it into my shed as I have CAT5e cables linking them. What I would like to do is set a scheduled relication so that not only does it copy the files, it copies the shares, user accounts and permissions (basically everything that is the NAS).
My idea is that if my NAS in my house ('NAS-1') breaks, I can change port redirection on my router for the NAS ('NAS-2') in the shed and it will continue to allow us to access our files (I know we would need to use '\\nas-2\FolderShareName' instead, but the FTP accounts would continue to work.
My NAS has 8+ FTP accounts which are used by web servers in the Cloud to backup the sites and databases to my NAS every 2 days, hence I realy need a DR solution. I have a UPS for my router and NAS in the house at the moment which helps.
Thanks all for your help.
Regards
Alan

I use daily rsync backup jobs for each share to do something similar. User accounts aren't migrated, but those rarely change, so I don't see much issue with just making the changes manually on both systems. Likewise I don't change the configuration often, so I do those manually also.
If GID/UIDs match for the users and groups, then rsync should preserve everything.
This is not quite the same as ReadyDR (snapshots won't be identical on the two NAS).
FWIW, I'd also use a UPS on the backup NAS in the shed.
StephenB Thanks for the info. Yes I have now purchased another UPS to go on the 'NAS-2' for the shed, it does make perfect sence. I couldn't get the rsync to work for love nore money. In the end, I took a config backup of 'NAS-1' and restored it to 'NAS-2' and changed the name. It restored all the usernames and shares, so I then created a bac kup job for each share fron 'NAS-1' to 'NAS-2'. It too a bit of time to set up, but then split the load over the 7 days so I know my network won't get hammered doing everything in one day. It was anoying I couldn't find a better way, but as you say, I won't need to create new users, shares or FTP accounts that often, so doesn't matter if I have to create them by hand on both units.
Thansk for your help.
Hi AlanWooler
ReadyDR only for shares' snapshots backup , not for two NAS ， and RN104 don't have ReadyDR , ReadyDR only on NAS with X86 chip
Thanks

-I wasn't meaning to imply that AlanWooler could use ReadyDR, I was just intending to point out that the snapshots on the two NAS would be different. I should have worded that sentence better.
-A ReadyDR job backs up snapshots from one share on NAS A to NAS B. So in a sense it is for two NAS. You would need two business class ReadyNAS, and you'd need one ReadyDR job for each share/lun.
CR Thank you for the info. Yes, I found this out the hard way.
