I was wondering how often does one choose to make and keep back ups. I know that “It depends on your business needs”, but that is rather vague and unsatisfying, so I was hoping to hear some heuristics from the community. Like say I had a workstation/desktop that is acting as a server at a shop (taking inventory / sales receipts) and would be using something like timeshift to keep snapshots. I feel like keeping two daily and a weekly would be alright for a store, since the two most recent would not be too old or something. I also feel like using the hourly snapshots would be too taxing on a CPU and might be using to much disk space.
stroj task runs daily the initial sync took forever tho because I only have 5MB UP connection
Every hour via Restic to a local Mino instance on my NAS. Once a day to backblaze B2. Once a week to an offline HDD in my fire safe.
Keep in mind the more often you backup the less total time each backup should take to run. If your backup software isn’t too heavy to run and stores backups incrementally, there is little penalty to frequent backups.
Whenever I’ve gone too far forwards
It depends what I’m backing up and where it’s backing up to.
I do local/lan backups at a much higher rate because there’s more bandwidth to spare and effectively free storage. So for those as often as every 10 mins if there are changes to back up.
For less critical things and/or cloud backups I have a less frequent schedule as losing more time on those is less critical and it costs more to store on the cloud.
I use Kopia for backups on all my servers and desktop/laptop.
I’ve been very happy with it, it’s FOSS and it saved my ass when Windows Update corrupted my bitlocker disk and I lost everything. That was also the last straw that put me on Linux full-time.
5 minutes after every computer boot to a NAS. Then nightly from the NAS to the cloud.
