readynas backup
Hi I have a readynas 312 with 2 2TB hard drives setup in Raid 1. I have hourly snapshots setup on my shares and I also have a USB external hard drive hooked up for daily backups. I realize that ...

For rsync, you can create a share on the USB drive, and use localhost (or 127.0.0.1) for the IP address.

Crashplan can be installed on the NAS (I have it running on my pro6 with OS 4). Memory can be a problem (and Crashplan uses 32 bit Java, so it is limited to ~ 4 GB).

Actually it does work - see https://support.code42.com/CrashPlan/4/Backup/Backing_Up_A_Windows_Network_Drive
Though it is "unsupported", so is running headless on a linux machine. I've found that Crashplan support will engage on failed backups, etc - though they won't help with the actual setup of the "unsupported" process.
This is simpler to set up than installing directly on the NAS (esp with the per-user installation), and doesn't have the memory issues that you can run into with the crashplan on linux.

Basically if something gets corrupted on the raid drive it will also happen to the USB drive... I just don't see how the USB backup is anymore of a backup than the RAID in the NAS.
If you are using the built-in backup, then the USB drive is simply another copy of what's on the internal disks. You are correct in thinking there are limitations to that approach.
Some cases where it helps:
(a) the NAS itself bricks - perhaps corrupting the RAID array.
(b) Recovery from a user error - for instance you accidently delete a share.
(c) If you are replacing a drive, and the remaining drive also fails the volume is lost.
In all these scenarios, the USB backup is likely intact.

Is there some way to setup the USB backup to archive deleted or altered files?
If you use rsync, you can set up the backup job to keep deleted files (in fact that is the default). You can't archive altered files easily (unless you rotate multiple USB drives).
My approach is to back up to another OS6 NAS, with snapshots turned on for the destination shares. As long as there is enough space for the snapshots, that provides the ability to roll back to older versions. My cloud backup software (Crashplan) also gives me the ability to recover old versions of files.
StephenB thank you for the good points. Yes my next job is tackling cloud backups. Our old server was setup with crashplan, but I haven't figured out how to use crashplan with the readynas yet. Crashplan wouldn't allow backing up network drive from a computer and the readynas doesn't have an app for crashplan backups.
I tried to do Rsync backups for the USB drive but during the setup of the backup it didn't give me any option to select the method of backup. Am I missing something here?
Thank you
