Agreed, but if you are looking into self hosting anything, whether internet connected or not, you should be following proper data backup and redundancy rules
The 321 data backup rule is to have three copies of everything across at least two different types of storage media, with one backup in a separate geographic location for emergencies.
For most people who self host, this means backing up primary devices to a NAS, then backing up the NAS to a backup service. This option is often cheaper than cloud storage in exchange for being more annoying to set up or recover from.
Also keep in mind that redundancy is not backup. All of your backup options should also be redundant. In a NAS, that means having additional drives with parity data so that if a drive fails, it can be replaced without losing anything, but that parity drive isn’t backup. Pretty much any backup service or cloud storage you use is going to be redundant, so making sure your local data is resilient is important.
