Selfhosted

What's my what lmao?

🤞

Are cyanide tablets a backup strategy?

Restic using resticprofile for scheduling and configuring it. I do frequent backups to my NAS and have a second schedule that pushes to Backblaze B2.

I run a restic backup to a local backup server that syncs most of the data (except the movie collection because it's too big). I also keep compressed config/db backups on the live server.

I eventually want to add a cloud platform to the mix, but for now this setup works fine

Can anyone ELI5 or link a decent reference? I'm pretty new to self hosting and now that I've finally got most of my services running the way I want, I live in constant fear of my system crashing

Irreplaceable media: NAS->Back blaze NAS->JBOD via duplicacy for versioning

Large ISOs that can be downloaded again, NAS -> JBOD and or NAS -> offline disks.

Stuff that's critical leaves the house, stuff that would just cost me a hell of a lot of personal time to rebuild just gets a copy or two.

I have an external hard drive that I keep in the car. I bring it in once a month and sync it with the server. The data partition is encrypted so that even if it were to get stolen, the data itself is safe.

I have a raspberry pi with an external drive with scripts to rsync each morning. Then I have S3 deep glacier backups for off site.

Personal files: Syncthing between all devices and a TrueNAS Scale NAS. TrueNAS does snapshots 4 times a day, with a retention policy of 30 days. From there, a nightly sync to Backblaze B2 happens, also with a 30 day retention policy. Occasional manual backups to external drives too.

Homelab/Servers: Proxmox VM and LXC container exports nightly to TrueNAS, with a retention policy of 7 days. A separate weekly export happens to a separate TrueNAS share, that gets synced to B2 weekly, with a retention policy of 30 says. Also has occasional external drive backups.

Large/important volumes on SAN-> B2.

Desktop Macs -> Time Machine on SAN & Backblaze (for a few)

Borgbackup is great and what we used for all our servers when they were pets. It's a great tool, very easy to script and use.

I use borgbackup + zabbix for monitoring.

At home, I have all my files get backed up to rsync.net since the price is lower for borg repos.

At work, I have a dedicated backup server running borgbackup that pulls backups from my servers and stores it locally as well as uploading to rsync.net. The local backup means restoring is faster, unless of course that dies.

Highly recommend borgbackup, I've been using it for years and it's always been smooth

I usually write my own scripts with rsync for backups since I already have my OS installs pretty much automated also with scripts.

Am I the only one using kopia :)?

Im quite new in selfohsting and backups. I went for duplicaty and it is perfect, but heared bad stories and now I use kopia daily backups to another drive and also to B2. Duplicaty is still doing daily backups, but only few important folders to google drive.

Ive heared only good stories about kopia and no one mentioned it

All devices backup to my NAS either in realtime or at short intervals throughout the day. I use recycling bins for easy restores for accidentally deleted files.

My NAS is set up on a RAID for drive redundancy (Synology RAID) and does regular backups to the cloud for active files.

Once a day I do a hyperbackup to an external HDD.

Once a month I backup to an external drive that lives offsite.

Backups to these external HDDs have versioning, so I can restore files from multiple months ago, if needed.

The biggest challenge is that as my NAS grows, it costs significantly more to expand my backups space. Cloud storage and new external drives aren't cheap. If I had an easy way to keep a separate NAS offsite, that would considerably reduce ongoing costs.

I use Borgbackup 1.2.x. It works really well. Significantly faster than Duplicity. Borg uses block-level deduplication instead of doing incremental backups, meaning the backup won't grow indefinitely like with duplicity (this is why you have to periodically do a full backup with Duplicity). The Borg server has an "append-only" mode meaning the client can only add data to the backup and not remove it - this is useful because if an attacker were to gain access to the client, they can't delete all your backups. This is a common issue with other backup systems - the client has full access to the backup, so there's nothing stopping an attacker from erasing the client system plus all its backups.

For storing the backups, I have two storage VPSes - One with HostHatch in Los Angeles ($10/month for 10TB space) and one with Servarica in Montreal Canada (3.5GB space for $84/year).

Each system being backed up performs the backup twice - Once to each VPS. Borgbackup recommends this approach over only performing one backup then rsyncing it to a different server. The idea is that if one backup gets corrupted (or deleted by an attacker, etc), the other one should still be OK as it's entirely separate.

I realized at one point that the amount of data that is truly irreplaceable to me amounts to only - 500GB. So for this important data I back up to my NAS, then from there backup to Backblaze. I also create M-Discs. Two sets, one for home and one I keep at a fiends’ place. Then because “why not” and I already had them sitting around I also backup to two sd cards and keep them on site and off site.

I also backup my other data like tv/movies/music/etc but the sheer volume of data gives me one option, that being a couple usb hard drives I back up to from my NAS.

I use.... Timeshift ->Local backup on to my RAID array borgbackup -> borgbase online backup GlusterFS -> experimenting with replicating certain apps across 2 raspberry pi's

I just wanted to say that I appreciate the input from everyone here. I really need to work on my backup solution and this will be helpful.

Main NAS backups to Secondary NAS (onsite - 10G link). Secondary NAS backups up to Offsite (Hetzner server) weekly. Only important data, not Linux ISOs etc.

Backup everything locally in proxmox on separate storage, another copy to a local nas and a third one to backblazes cloud storage.

Daily offsite to a backup server via restic (+ a self written wrapper for multiple targets). Restic can also run with anything else (sftp, s3 APIs etc). Kinda modern duplicity / borg. Full encrypted and incremental.

I use a Backuppc instance hosted on an off site server with a 1Tb drive. It connects through ssh to all my vms and backups /home and any other folders i may need. It handles full and incremental backups, deduplication, and compression.

Personally I do:

• Daily snapshots of my data + Daily restic backup on-site on a different machine
• Daily VM/containers snapshot locally and on a different machine, keeping at least 2 monthly, 2 weekly and 2 daily backups
• Weekly incremental data backup in an immutable B2 bucket, with a new bucket every month and a 6 month immutability (so data can't be changed/erased for 6 month)
• Weekly incremental data backup on an other off-site machine
• Monthly (but I should start doing it weekly) backup of important data (mainly documents and photos) on removable medias that I keep offline in a fire-proof safe

Maybe it's overkill, maybe it's not enough, I'll know when something fail and I am screwed, ahah

As a note, everybody should test/check their backup frequently. I once had an issue after changing an IP address and figured out half my backups where not working 6 month later...

My critical files and folders are synced from my mas to my desktop using syncthing. From there I use backblaze to do a full desktop backup nightly.

My Nas is in raid 5, but that's technically not a backup.

I back up my home folder to an encrypted drive once a week using rsync, then I create a tarball, encrypt it, and upload it to protondrive just in case.

For PCs, Daily incremental backups to local storage, daily syncs to my main unRAID server, and weekly off-site copies to a raspberry pi with a large external HDD running at a family member's place. The unRAID server itself has it's config backed up to the unRAID servers and all the local docker stores also to the off-site pi. The most important stuff (pictures, recovery phrases, etc) is further backed up in Google drive.

All nextcloud data gets mirrored with rsync to a second drive, so it's in 3 places, original source and twice on the server

Databases are backed up nightly by webmin to second drive

Then installations, databases etc are sent to backblaze storage with duplicati

Rsync script that does deltas per day using hardlinks. Found on the Arch wiki. Works like a charm.

Cross my fingers 🤞

I use syncthing to sync files between phone, pc and server.

The server runs proxmox, with a proxmox backup server in VM. A raspberry pi pulls the backups to an usb ssd, and also rclone them to backblaze.

Syncthing is nice. I don't backup my pc, as it is done by the server. Reinstalling the pc requires almost no preparation, just set up syncthing again

Holy crap. Duplicity is what I've been missing my entire life. Thank you for this.

In short: crontab, rsync, a local and a remote raspberry pi and cryptfs on usb-sticks.
