Rsnapshot to an external USB drive.
Probably not the best, but it works for my little 6TB OpenMediaVault server with some Docker thrown in.

Encrypted backup to google drive weekly from unraid, planning to get a NAS for another backup location
Duplicati. Works like a charm. Supports practically every backend (S3, backblaze, one drive, Google, storj, sia, even Tahoe!
A lot of services have some kind of way to create backup files. I have cronjobs doing that daily then uploading it to some cloud storage with rclone.
I've gotten decent results from s3cmd sync.
For my workstation I'm using a small script that packs and compresses all relevant directories with tar once a week. The resulting file is then copied to a local backup drive and to my NAS. An encrypted version of that file is sent to an offsite VPS.
For my selfhosted services (on Proxmox) I'm using ProxmoxBackupServer.
my solution is syncthing
I don't know if it's a smart solution but I have a HDD in my server that is used just for backups, each night I have rsync automatically moving stuff from multiple locations that I want to back up onto the drive. After that is done I have Kopia backup to B2, with compression, deduplication and encryption. I use healthchecks.io as well to alert me if any of the steps fails to complete (but none of the steps block each other).
I have an old synology DS1513+
it runs Active Backup for business and Active backup for google workspace, as well as an AFP share for Apple machines. This is about 95% of all backups. Those backup archive files are then ALSO backed up to one of two large 14TB hdds. I swap them out monthly (or thereabout) and keep the spare at my office or in my firesafe when at home.
I have a couple other things out there too. A small SSh box to handle some scripting of config file backups etc. My main synology 1815+ also has a cloud sync up to backblaze that happens in realtime, but only keeps 1 copy of stuff as well as a hyperbackup job for super important stuff up to Backblaze, in addition to the nightly backups to the 1513+. This way if my house burns down I still have something (and likely a full copy with the 14TB HDD)
For containers (but I use k3s) I use git to store helmfiles and configuration, secrets in ci/cd system.
For the rest - I use autorestic that backups data over ssh and S3.
ZFS send to a pair of mirrored HDDs on the same machine ever hour and a daily restic backup to S3 storage. Every six months I test and verify the cloud backup.
raid1 + data duplication
Photos, videos, music, documents, etc.. are available on multiple devices using SyncThing.

Thanks! I just started setting up NixOS on my laptop and I'm planning to use it for servers next. Saving this for later!
