I am trying to setup a simple local backup strategy for my home network/config and wanted to get some tips and ideas. I think I have most of the config setup - just need some help with the strategy/approach.
This is my setup:
Mac mini - main server / computer. wired to network. has internal SSD (macOS - APFS) + 2TB internal storage (DATA - Mac OS extended)
Rock64 - primary NAS (OMV4). wired to network. 3TB storage (2 disks as single drive using btrfs) thanks @tkaiser for instruction on how to set this up
RPI3 - data backup NAS (OMV4). wired to network. 2TB storage (1 disk using btrfs) - for redundancy
What I think I should do is...
1. backup important stuff from my mac (iPhoto library iTunes, Docs etc) from the SSD to the 2TB internal storage on the same Mac (daily) - using a backup app called Get Backup Pro...
2. use rsync on primary NAS to copy/sync data from Mac to the NAS (daily)
3. use rsync on backup NAS to copy/sync data from primary NAS to the backup NAS (weekly) - as a redundant copy.
I am not using Time Machine on my Mac as I have had trouble with backing up time machine to the NAS (permissions, locked files etc)
My key question is really about handling incremental backups from my Mac to the NAS. I think there are issues with hard links when these are backed up to a NAS.
Once I get everything working locally, the plan is to move the data backup NAS offsite.
Thoughts and suggestions welcomed!
