    It’s not a drawback because rsync has supported incremental versioned backups for over a decade, you just have to use the --link-dest flag and add a couple lines of code around it for management.

    Sure, but that's not in their answer.

      They didn't provide an rsync example until later in the post, the comment about not supporting differential backups is in reference to using rsync itself, which is incorrect, because rsync does support differential backups.

      I agree with you that not doing differential backups is a problem, I'm simply commenting that this is not a drawback of using rsync, it's an implementation problem on the user's part. It would be like somebody saying "I like my Rav4, it's just problematic because I don't go to the grocery store with it" and someone else saying "that's a big drawback, the grocery store has a lot of important items and you need to be able to go to it". While true, it's based on a faulty premise, because of course a Rav4 can go to the grocery store like any other car, it's a non-issue to begin with. OP just needs to fix their backup script to start doing differential backups.

        I recently implemented a backup workflow for me. I heavily use restic for desktop backup and for a full system backup of my local server.
        It works amazingly good. I always have a versioned backup without a lot of redundant data. It is fast, encrypted and compressed.

        But I wondered, how do you guys do your backups? What software do you use? How often do you do them and what workflow do you use for it?

        Right now, nothing 😈 (but my dotfiles/etc configs live on several machines)

        Before, I used Restic (incremental, encrypted backup over network), which I really liked. I think I should set it up again.

          My one and only purpose was to warn them that their "drawback" is more of a gator pit. It's noble that you're here defending rsync's honor, but maybe let them know instead? My preferred backup tool has "don't eat my data" mode on by default.

            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.

            The restore process takes forever and sometimes fails. Last time I was forced to try every daily backup to several days before last backup to find one that could actually be restored. I have switched to borg (using Pika Backup for desktop and Borgmatic for servers). No restores have failed since.

              All my configs are in gitlab or a self hosted forgejo server and all files are in seafile or a self hosted service running on proxmox. Then I use proxmox backup server on a storage VPS for off-site backup

                  I have a server with a RAID-1 array, that makes daily, weekly, and monthly read only btrfs snapshots. The whole thing (sans snapshots) is sync'd with syncthing to two rPi's in two different geographic locations.

                  I know neither raid nor syncthing are "real" backup solutions, but with so many copies of the files living in so many locations (in addition to my phone, laptop, etc.) I'm reasonably confident its a decent solution.

                    Borg Backup, whenever I feel like it - usually monthly.

                      I use external drive for my important data and if my system is borked (which never happen to me) I just reinstall the OS

                              External drives are more prone to damage and failures, both because they're more likely to be dropped/bumped/spilled on etc, and because of generally cheaper construction compared to internal drives. In the case of SSDs the difference might be negligible, but I suggest you at least make a copy on another "cold" external drive if the data is actually important

                                I use Duplicacy to backup to my TrueNAS server. Crucial data like documents are backed up a second time to my GDrive, also using Duplicacy. Sadly it's a paid solution, but it works great for me.

                                  Borg daily to the local drive then copied across to a USB drive, then weekly to cloud storage. Script is triggered by daily runs of topgrade before I do any updates

                                    I created a script that I dropped into /etc/cron.hourly which does the following:

                                    1. Use rsync to mirror my root partition to a btrfs partition on another hard drive (which only updates modified files).
                                    2. Use btrfs subvolume snapshot to create a snapshot of that mirror (which only uses additional storage for modified files).
                                    3. Moves "old" snapshots into a trash directory so I can delete them later if I want to save space.

                                    It is as follows:

                                    #!/usr/bin/env python
                                    from datetime import datetime, timedelta
                                    import os
                                    import pathlib
                                    import shutil
                                    import subprocess
                                    import sys
                                    
                                    import portalocker
                                    
                                    DATETIME_FORMAT = '%Y-%m-%d-%H%M'
                                    BACKUP_DIRECTORY = pathlib.Path('/backups/internal')
                                    MIRROR_DIRECTORY = BACKUP_DIRECTORY / 'mirror'
                                    SNAPSHOT_DIRECTORY = BACKUP_DIRECTORY / 'snapshots'

                                      I recently implemented a backup workflow for me. I heavily use restic for desktop backup and for a full system backup of my local server.
                                      It works amazingly good. I always have a versioned backup without a lot of redundant data. It is fast, encrypted and compressed.

                                      But I wondered, how do you guys do your backups? What software do you use? How often do you do them and what workflow do you use for it?

                                      I use Pika Backup (GUI that uses Borg Backup on the backend) to back up my desktop to my home server daily, then overnight that server has a daily backup using Borg to a Hetzner Storage Box. It's easy to set it and forget it (other than maybe verifying the backups every once in a while), and having that off site back up gives me peace of mind.

                                        • daily important stuff (job stuff, Documents folder, Renoise mods) is kept synced between laptop, desktop and home server via Syncthing. A vimwiki additionally also on the phone. Sync happens only when on home network.

                                        • the rest of the laptop and desktop I'll roll into a tar backup every now and then with a quick bash alias. The tar files also get synced onto home server's big file system (2 TB ssd) via Syncthing.

                                        • clever thing is that the 2 TB ssd replaced an old 2 TB spinning disk. I kept the old disk and set up a systemd thing that keeps it spun down, but starts and mounts it once a week and rsyncs the changes to the ssd over, then unmounts it so that it sleeps again for a week. That old drive is likely to serve for years still with this frugal use.

                                        How do you make sure the disk spins down? Is unmounting enough?

                                          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.

                                          Do you use some kind of encryption on the VPS?
