My KVM hosts use “virsh backup begin” to make full backups nightly.

All machines, including the KVM hosts and laptops, use rsync with --link-dest to create daily incremental versioned backups on my main backup server.

The main backup server pushes client-side encrypted backups which include the latest daily snapshot for every system to rsync.net via Borg.

I also have 2 DASs with 2 22TB encrypted drives in each. One of these is plugged into the backup server while the other one sits powered off in a drawer in my desk at work. The main backup server pushes all backups to this DAS weekly and I swap the two DASs ~monthly so the one in my desk at work is never more than a month or so out of date.

My kmymoney file goes on an old compact flash memory card.

My home directory (including that file), /etc, databases, and a few other things get backed up weekly on to a USB stick.

Media raid array is automatically backed up to a large drive in another computer each evening. (The raid5 array isn’t that large. It was when I built it, but now I can buy a single drive that is nearly as large as the array…)

Pictures are backed up to Amazon’s glacier deep freeze. I pay about $1/month to back up all of my pictures. I intend to put other important things there too but haven’t gotten there yet.

Borg to a NAS.

500GB of that NAS is “special” so I then rsync that to a 500GB old laptop hdd, of which is is duplicated again to another 500GB old laptop hdd.

Same 500GB rsync’d to Cloud Server.

I use BorgBackup with Vorta for a GUI, and I keep the 3-2-1 backup rule for important stuff (IE: 3 copies, 2 on different media, 1 off-site.)

I want to say I’m glad you asked this and thank you for asking. In this day and age there are a lot of valid concerns for privacy and anonymity and the result is that people do not share how their system(s) work, not openly or very often. I’m still fairly new to Linux (3.5 years) and at times, I feel like I am doing everything wrong and that there is probably a better way. Posts like these help me learn about possible improvements or mistakes I might have made.

I previously used Vorta with Borgbackup locally, automatically backing up my Home (sans things like .cache and .mozilla) to a secondary internal drive every other day. I also would manually back up a smaller set of important documents (memes and porn #joke) to a USB flash drive, to keep on my person, which also would be copied across several cloud storage providers (dropbox, mega, proton), depending on how much space their free versions provided, with items removed according to how much I trusted the provider.

Then I built a new system. In the process of setting it all up, I had a few hiccups. It took longer than I expected to have a stable system. That was over a year ago (stat / …Birth: 2024-02-05 04:20:53…) and I still haven’t gotten around to setting up any backup system on it. I want to rethink my old solution and this post is useful for learning about the options available. It’s also a reminder to get it done before it is too late. Where I live, tornado season in starting. I lost a lot in 2019 after my city had 4 tornados in one day.

I rsync ~/ to a USB nub. A no brainer.

My conclusion after researching this a while ago is that the good options are Borg and Restic. Both give you incremental backups with cheap timewise snapshots. They are quite similar to each other, and I don’t know of a compelling reason to pick one over the other.

rsync 😪

Backup? What?

i do backups of my home folder with Vorta, tha uses borg in the backend. I never tried restic, but borg is the first incremental backup utility i tried that doesnt increase the backup size when i move or rename a file. I was using backintime before to backup 500gb on a 750gb drive and if I moved 300gb to a different folder, it would try to copy those 300gb again onto the backup drive and fail for lack of storage, while borg handles it beautifully.

as an offsite solution, i use syncthing to mirror my files to a pc at my fathers house that is turned on just once in a while to save power and disc longevity.

I’m curious, is there a reason why noone uses deja-dup? I use it with an external SSD on Ubuntu and (receently) Mint, where it comes pre-installed, and did not encounter Problems.

Since most of the machines I need to backup are VMs, I do it by the means of hypervisor. I’d use borg scheduled in crontab for physical ones.

for my server I use proxmox backup server to an external HDD for my containers, and I back up media monthly to an encrypted cold drive.

For my desktop? I use a mix of syncthing (which goes to the server) and windows file history(if I logged into the windows partition) and I want to get timeshift working I just have so much data that it’s hard to manage so currently I’ll just shed some tears if my Linux system fails

I recently switched to Kopia for my offsite backup solution.

It’s apparently one of the faster options, and it can be set up so that the files of the differential backups are handled by a repository server on the offsite end, so file management doesn’t need to happen over the network at a snails pace.

The result is a way to maintain frequent full backups of my nextcloud instance, with almost no downtime.

Nextcloud only goes into maintenance mode for the duration of a postgres database dump, after which the actual file system backup occurs using a temporary btrfs snapshot, containing a frozen filesystem at the time of the database dump.
