The built-in database backup and restore feature in Kitten¹ (that actually works and is in the Kitten Settings section of every Kitten app) just saved my ass (again) :)

Thank you, past me ;)

@happyborg @dalai @jwildeboer most of these providers claim that they can recoup the cost with new purchases and shrinking costs for storage over time, which makes this truly a #PyramidScheme.

• OFC they also throtthe users and don't expect everyone to max out their purchased storage quota instantly.

• But I'm not just comparing against short-term filehosters but also in terms of #backups consider years, if not decades of uptime to be necessary to be useful.

Also mind you this ain't like #TeamViewer where the cost of infrastructure is negligible (just some "Rendrevous-Server" to exchange status info, IP addresses and facilitate "Hole Pubching" through #NAT & #Firewall which in theory doesn't reuire mich compute and bandwith to function.

• We're talking Gigabytes if not Terabytes per User in storage and traffic.

• And since this system isn't like some #ColdStorage like a #tape, this needs to be #HDDs that constantly spin and draw power.

@happyborg @dalai @jwildeboer I'd not trust any "one time purchase" cloud storage because that model is unsustainable by virtue of recurring costs!

• If one's already holding classes for #IT, it's either feasible to organize some (quota'd!) storage (i.e. #SSH access to a server) or expect the class members to have i.e. some cheap external HDD for that.

• I don't expect them to backup several terabytes of data and if they need to, then there should certainly be budget for either S3 block storage and a cheap VPS or a "Storage VPS"…

Not to mention there's need to not just backup files, but databases.

• #IPFS is IMHO not great for #Backups, but merely a tool to distribute large files across multiple nodes (similar to #BitTorrent #MagnetLinks).

[Fediverse BackUp]

Could an ActivityPub / ActivityStreams file be a "good" format for backing up a post?

(I.e., what I call an "Activity File". I.e., the file that has a media-type of "application/activity+json".)

[Fediverse BackUp]

So, I think an (ActivityPub / ActivityStreams) Activity File COULD be a "good" format for backing-up a single post on the Fediverse, but —

Most (maybe all) extant Fediverse software would need to change a bit. Fediverse software would need to support embedding "everything" in a single Activity File (rather than referring to "everything" else by URLs).

Also — what about comments / replies —

Someone people (including me) would want at least some of the comments / replies to be included in a BackUp for a post.

So, for an Activity File to be a "good" format for a BackUp, a single Activity File would also need to contain (all or selected) the comments / replies to the post.

Also — we would need to consider Threads / Storms —

Where people reply to their own post to make a larger post made up of smaller posts.

(I.e., what I have been doing here 🙂 )

For an Activity File to be a "good" format for a BackUp, a single Activity File would need to contain all the posts in the Thread / Storm.

But — for an Activity File to be a "good" format for a BackUp, there would need to be a way to get the Fediverse software to embed the (non-text) media (such as images, audio, video, etc) into an Activity File.

Also —

Now, having said that, I don't think there is anything about ActivityPub / ActivityStreams that "prevents" Fediverse software from not embedding (non-text) media (such as images, audio, video, etc) into an Activity File —

For example, an "Image" Object can contain a ("mediaType" and a) "content" field (rather than an "href" field).

But —

[Fediverse BackUp]

If you wanted to BackUp a post on the Fediverse, and all you download was the Activity File (with URLs pointing to the non-text media), then — you lost all the (non-text) media (such as images, audio, video, etc) that were part of the post.

Which would be bad.

[Fediverse BackUp]

I think one challenge, in practice, with using an Activity File as a BackUp Format is that — a lot of Fediverse software does NOT embed (non-text) media (such images, audio, video, etc) in the Activity File.

But, instead references them using URLs.

(And, by "URL" I mean "URI", "IRI", etc.)

Usually this is probably a good thing, but —

@signalapp introduced secure #backups: https://signal.org/blog/introducing-secure-backups/

It's available in my Android app already (still Beta).

If you would like to have more than 45 days in your backup, you can subscribe for 1,99€/month in order to get backup up to 100GB.

I do think that this is a fair price and you'd support #Signal which offers a very important service to our society, not only in a technical sense. 👍 Example: https://cybernews.com/security/signal-germany-capitulate-client-side-scanning/

The more years I spend with computers, the more I realize the importance of storing the same piece of data in multiple independent places.

Note to self:
Computers are computers, whether you are using them for work or for personal purposes. Your personal computers need #backups just as much as the work ones do.
