lurch , to linux in backups for SD card disk image? that don't take up tonnes of space and can be rolled back?

clonezilla comes with multiple tools to copy entire disks to images, but only copying used blocks.

RedSquadCampFollower OP ,

the clonezilla website clonezilla.org says

Differential/incremental backup is not implemented yet.

@communism@lemmy.ml avatar

Proton for personal email. Not immediately needing to escape but once my free email runs out of storage I plan to switch to something else because of the concerns raised by the incident with the French climate activist.

Originally across multiple 4tb external drives but been mostly pushed to one nas 8tb drive in my case.

Paper drinking straws

Silly, but I like those because I can eat bits of it after using them :3

My guy, pasta drinking straws are for you!

Anarchistcowboy , to linux in What is something you want to use, yet are NOT using?

Nginx. I’m going to learn soon but I’m still new and it seems easy to screw up exposing things to the Internet.

QuizzaciousOtter ,

If you have to learn from scratch anyway I would consider caddy and traefik. I think those might be a bit more modern and user-friendly than nginx.

Shdwdrgn , to linux in backups for SD card disk image? that don't take up tonnes of space and can be rolled back?

I’m not sure about anything that does rolling backups of full disks, but I have used rdiff-backup for years for rolling backups of individual files. The format for the backup is similar to (and based on) rsync so it’s fairly easy to script. For complete servers I just keep a copy of the install image on hand, in a catastrophic drive failure I can do a new installation to a new drive (creating the partitions, grub setup, etc), then restore the latest backup. An alternative might be to use dd and create a full drive image file to use as your starting point in a full recovery.

One thing to keep in mind though is that the backups should NOT contain any system folders like dev or proc that get generated at boot. If possible, when making a starting image with dd, you want the drive to be separate and not part of the running OS, because some folders like dev and var have a basic set of files in place needed for the boot process which may be different than the final version you see after the OS is up and running. That’s why I find it easier to just plan around a clean install to new drives when needed.

RedSquadCampFollower OP ,

Thanks I will look at rdiff. I am not sure if rsync is able to “see inside” the *.img files to discern the individual files. If it can then it would be helpful because I could just re-write the same file over and over again and keep backups using rsync or any of the various rsync-derrived tools?

The filesystem will be cold at time of back up because I will need to shut it down, remove the card from the console and put it into my computer’s reader so no worries about that.

tkk13909 , to linux in backups for SD card disk image? that don't take up tonnes of space and can be rolled back?

If it’s a filesystem, it can be backed up using BorgBackup. There are a few different clients but I personally use Vorta on Linux.

dan ,
@dan@upvote.au avatar

+1 Borgbackup is great, and its deduplication works very well. Vorta works well, and there’s also GNOME Pika which has a very simple UI. For servers, I use Borgmatic.

RedSquadCampFollower OP ,

@tkk13909 @dan

Borg backup has insane deduping. The first time I used it I thought it was broken because of how much smaller the backup was compared to the original. I used it with vorta GUI.

I am not sure how to combine the task of making a disk image with backing up with borg either on the command line or via one of the GUIs?

chameleon ,
@chameleon@fedia.io avatar

Easiest way would be to use borg create --read-special --chunker-params fixed,4194304 '/home/user/sdcardbackup::{now}' /dev/sdX (which I copied from the examples in the documentation). I'm not sure if Vorta has a way to activate --read-special but I suspect not; you can most likely still use it to make the repo and manage archives inside of it though.

Backing up from a command/stdin might also be relevant as an alternative, since that lets you back up more or less anything.

dan ,
@dan@upvote.au avatar

Wow I love this - I never thought of directly backing up block devices like that.

OpenStars , to fediverse in what happened to kbin?
@OpenStars@discuss.online avatar

Pretty much, as others have explained here. I wanted to add that in addition to its fork Mbin there is also the Sublinks project to make a new implementation of the ActivityPub protocol and thus surf the Fediverse independent of Lemmy. sublinks.org (link to GitHub there too)

ProdigalFrog ,

Piefed is another Lemmy compatible alternative that looks quite promising: piefed.social

OpenStars ,
@OpenStars@discuss.online avatar

Thank you, I keep mixing it up with Pixelfed in my mind and forget that it exists:-).

It looks both really primitive (e.g. comment from Rima about lack of moderation tools) yet also extremely sophisticated at the same time. Like for me the upper right hand menu bar disappears entirely in dark mode (Android Firefox) - it seems still fully functional but I could not see it to know to click under most conditions - but those category arrangements and how they improve discoverability, it just makes so much sense!

Wow, now I’m as excited about this project as about Sublinks:-).

ProdigalFrog ,

Yes, those image layouts are fantastic for art communities! It definitely still has a lot of rough edges, UI wise.

I think he’s made some good strides with the mod tools, as seen here: piefed.social/post/167045

I’m glad we have a couple promising alternatives, and it’ll be exciting to see how they evolve differently ^^

OpenStars ,
@OpenStars@discuss.online avatar

Oh wow, community wikis with version history even - that’s fantastic.

Best of all though seems to be that it is in a language that people actually use - no disrespect to Rust bc it’s arguably the best, certainly the hottest language right now, but it definitely seems to be limiting progress that so few people are willing to learn it.
