Linux

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.

I keep all of my documents on a local server so all that is on any of my computers is software. So if I need to reinstall Linux I cab just do it without wording about losing anything.

Nice try, mister ransonware attacker hacker!

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.

Timeshift for snapshots and deja backups for files

My work flow is pretty similar to yours:

For my desktop and laptops: systemd timer and service that backups every 15 minutes using restic to my NAS.

For my NAS : daily backup using restic + ZFS snapshots.

All restic backups are then uploaded daily to Backblaze B2.

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.

I've found that the easiest and most effective way to backup is with an rsync cron job. It's super easy to setup (I had no prior experience with either rsync or cron and it took me 10 minutes) and to configure. The only drawback is that it doesn't create differential backups, but the full task takes less than a minute every day so I don't consider that a problem. But do note that I only backup my home folder, not the full system.

For reference, this is the full line I use: sync -rau --delete --exclude-from='/home//.rsync-exclude' /home/ /mnt/Data/Safety/rsync-myhome

".rsync-exclude" is a file that lists all files and directories I don't want to backup, such as temp or cache folders.

(Edit: two stupid errors.)

I recently bought a storagebox from Hatzner and set up my server to run borgmatic every day to backup to it.

I've also discovered that Pika Backup works really well as a "read only" graphical browser for borg repos.

Most of my data are on 2x16TB HDDs running an mdraid1 and then I backup it all to a usb drive with Borg Backup.
The os.qcow2 files live on my m.2 NVMe and are manually backuped to the mdraid1 before running the borg backup.
I should automate the borg backup but currently I just do it manually a few times a month.
Would also like to have two usb drives and keep one offline in another part of the house but that's another future project.

This looks a bit like borgbackup. It is also versioned and stores everything deduplicated, supports encryption and can be mounted using fuse.

My systems are all on btrfs, so I make use of subvolumes and use brkbk to backup snapshots to other locations.
