Selfhosted

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

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

btrfs and btrbk work very well, tutorial: https://mutschler.dev/linux/fedora-btrfs-35/

Nextcloud with folder sync for both mobile and PC, backs up everything I need.

On my home network, devices are backed up using Time Machine over the network. I also use Backblaze to make a second backup of data to their cloud service, using my own private key. Lastly, I throw some backups on a USB drive that I keep in a fire safe.

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

I just use duplicity and upload to Google drive.

I backup an encrypted and heavily compressed archive to my local nas and to google drive every night. NAS keeps the version from the first of every month and 7 days prior history and google drive just the latest

I use backupninja for the scheduling and management of all the processes. The actual backups are done by rsync, rdiff, borg, and the b2 tool from backblaze depending on the type and destination of the data. I back up everything to a second internal drive, an external drive, and a backblaze bucket for the most critical stuff. Backupninja manages multiple snapshots within the borg repository, and rdiff lets me only copy new data for the large directories.

For smaller backups <10GB ea. I run a 3 phased approach

• rsync to a local folder /srv/backup/
• rsync that to a remote nas
• rclone that to a b2 bucket

These scripts run on the cron service and I log this info out to a file using --log-file option for rsync/rclone so I can do spot checks of the results

This way I have access to the data locally if the network is down, remotely on a different networked machine for any other device that can browse it, and finally an offsite cloud backup.

Doing this setup manually through rsync/rclone has been important to get the domain knowledge to think about the overall process; scheduling multiple backups at different times overnight to not overload the drive and network, ensuring versioning is stored for files that might require it and ensuring I am not using too many api calls for B2.

For large media backups >200GB I only use the rclone script and set it to run for 3hrs every night after all the more important backups are finished. Its not important I get it done asap but a steady drip of any changes up to b2 matters more.

My next steps is to maybe figure out a process to email the backup logs every so often or look into a full application to take over with better error catching capabilities.

For any service/process that has a backup this way I try and document a spot testing process to confirmed it works every 6months:

• For my important documents I will add an entry to my keepass db, run the backup, navigate to the cloud service and download the new version of the db and confirm the recently added entry is present.
• For an application I will run through a restore process and confirm certain config or data is present in the newly deployed app. This also forces me to have a fast restore script I can follow for any app if I need to do this every 6months.

My important data is backed up via Synology DSM Hyper backup to:

• Local external HDD attached via USB.
• Remote to backblaze (costs about $1/month for ~100gb of data)

I also have proxmox backup server backup all the VM/CTs every few hours to the same external HDD used above, however these backups aren't crucial, it would just be helpful to rebuild if something went down.

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

I don't backup my personal files since they are all more or less contained in Proton Drive. I do run a handful of small databases, which i back up to ... telegram.

For my server I use duplicity, with a daily incremental backup and sending the encrypted diffs away. I researched a few more options some time ago but nothing really fit my use case, but I'm also not super happy with duplicity. Thanks for suggesting borgbackup.

For my personal data I have a NextCloud on a RPi4 at my parents' place, which also syncs between my laptop that I've left there. For an offline and off-site storage, I use the good old strategy where I bring over an external hard drive, rsync it, and bring it back.

Got a Veeam community instance running on each of my VMware nodes, backing up 9-10 VMs each.

Using Cloudberry for my desktop, laptop and a couple Windows VMs.

Borg for non-VMware Linux servers/VMs, including my WSL instances, game/AI baremetal rig, and some Proxmox VMs I've got hosted with a friend.

Each backup agent dumps its backups into a share on my nas, which then has a cron task to do weekly uploads to GDrive. I also manually do a monthly copy to an HDD and store it off-site with a friend.

In the process of moving stuff over to Backblaze. Home PCs, few clients PCs, client websites all pointing at it now, happy with the service and price. Two unraid instances push the most important data to an azure storage a/c - but imagine i'll move that to BB soon as well.
Docker backups are similar to post above, tarball the whole thing weekly as a get out of jail card - this is not ideal but works for now until i can give it some more attention.

*i have no link to BB other than being a customer who wanted to reduce reliance on scripts and move stuff out of azure for cost reasons.

As I have all my data on my homeserver in VMs it’s currently only daily backups to the NAS with proxmox, but I should really add some remote NAS to have it backed up in case my local NAS breaks down.

Backing up to backblaze with duplicacy

Veeam community for me. Cross backup locally between my 2 servers at home, and then a copy job to an offsite NAS.

Have had to restorations before, and never had any issues.

TIme Machine.

For the 14 pcs (~8 regularly used) in my house I'm running daily backups with Synology Active for Backup to a spinning disk DiskStation, file sync of the User directory using Synology Drive to an SSD DiskStation (also backed up to HDD DS). That data is all deduplicated. Then additionally I've got a few custom scripts to keep programs up to date using Chocolatey and winget which then export the list of installed programs ready to be reinstalled on a new machine.

This allows me to either do full device restores or clean installs where the reinstall of the relevant programs is handled automatically and then it's just setting up sync/backup/office activation and we're off to the races.

Eager to nurture more pet projects, I wrote a python package to handle uncommon backups, derived from this this, I have various python scripts that I run periodically to copy things like:

• Photos/files from my phone
• Git repos
• Youtube playlists
• Conversations with chatGPT
• Notion databases
• Files from FTP servers
• Pipy/npm packages

And of course, files/directories from my computer. This can be configured to copy things to one or various drives, and in the future I would like to add some encryption mechanism for sensitive data. On top of this I share some files across computers using mega, but I should consider switching to syncthing
