I know this is more of a NAS question, but I figured there are a lot of smart people on here and this forum is a lot more active than the Netgear forum so I thought I would give it a shot here. I hope it’s not too off-topic.
I have a ReadyNAS 2304 that I bought for my business to backup some data, but I figured I would use it to backup my HassIO snapshots as well. I am using the Auto Backup integration from HACS to create and manage the backup files. This deletes certain files when they get to a certain age and seems to work great. When I have my NAS back up that folder, it only adds the new files and doesn’t remove the deleted files on the NAS. I am connected to HassIO via SMB from the ReadyNAS and I don’t see any options in the settings to purge old files or remove deleted files. All of my reading seems to show that I need to use rsync in order to accomplish this, but that seems silly to have an auto backup on a NAS that can only add files and not remove them for you.
Does anyone have any experience with ReadyNAS and know how to accomplish what I am looking to do?
