ReadyNAS Question Before Purchase
I currently have a ReadyNAS 628X in my home which is working well. Other than the RAID 5 setup, I don't have a true backup solution. I am considering purchasing a second ReadyNAS to use as my backu...
Thanks for all the advice and suggestions, though my head is spinning a bit. :smileyembarrassed:
Is rsync the same as Resilio Sync? I don't see rsync listed on the available apps page. Also, if I understand correctly, you turn off snapshots on your main NAS and only have them enabled on your backup NAS?
I thought the remote backup was the most secure idea, but perhaps I should just accept using a local backup. Granted, a fire or theft could ruin everything, but those are pretty unlikely events. The local backup would be easier and provide faster restoration if needed.

I have snapshots enabled on both the main NAS and the backup. The snapshots are taken shortly before the nightly backup is done.
The backup NAS is also on a power schedule, so it is turned off most of the day. Having snapshots enabled on the main NAS makes it simpler to access the previous versions.
Now that I better understand snapshots, I don't think I really need them. I use Acronis True Image on my computers to perform frequent, incremental backups to the NAS. Plus I just noticed that my snapishots are taking up more space than my actual data. Besides the backups, I only use the NAS to host movies, music, pictures, videos for my PLEX server. Those stable items only change when I add something new.
Is there a way to globally turn off snapshots? So far I've only found the schedule setting for each share where you can choose "never" from the drop down menu.
Also, how do you reclaim your snapshot storage space? Will those shapshots go away once snapshots are turned off?
Finally, do you know if the Netgear replicate app would still work fine for cloning your NAS locally? Did they just remove the remote option? Thanks.

I use TrueImage as well - making incremental image backups every week of 4 PCs. I still have snapshots on the TrueImage destination, but that is set to 2 weeks, not three months. The rationale there is to cover the scenario where I discover a new backup is corrupted right after the older backup set was deleted.
The thing about the snapshots on your other shares is that they only take up space when files are modified or deleted. So the snapshots are basically free on those shares.

I use custom snapshots, scheduled at 11 pm every day. "Only take snapshots with changes" is checked (just to eliminate clutter). Retention is generally set to 3 months (the TrueImage share being one exception, I have one other share that has snapshots turned off).
The snapshots are automatically deleted when the retention period expires. But they aren't deleted when you manually turn snapshots off - you have to delete them from the web UI.
"Smart" snapshots aren't so smart in my view. The snapshot thinning is a interesting idea, but the monthly snapshots are never deleted. And the oldest snapshots generally take the most space, since they are most diverged from the current share. (So when you are deleting snapshots, you should start with the oldest).
BTW, space isn't always reclaimed instantly with btrfs. And to maximize the free space you need to run a balance from the volume settings wheel from time to time. I schedule a balance every 3 months. FWIW, the longer a balance takes, the more the system needs it. So if the balance is taking too long you should run them more often.

No there is not.

It's not available anymore - ReadyDR was intended to be the replacement for it.
