BorgBackup

https://borgbackup.readthedocs.io/en/stable/

Timeshift is nice to make things easy. I simply use good old-fashioned rsync tied to a cron job.

For personal files I use Borg (with Vorta) and/or Restic

Syncthing. I don't want to invest into a NAS and put some load into my already greedy power bill, so I chose something decentralized. Syncthing really just works like Torrent but for your personal files: Whatever happens on the computer, also does on the phone, and on the laptop. Each have about 1TB of space and 3 times redundancy? Hell yea buddy dig in.

Restic. Borg also great.

I am using Borg for years. So far, the tool has not let me down. I store the backups on external hard drives that are only used for backups. In addition, I save really important data at rsync.net and at Hetzer in a storage box. Which is not a problem because Borg automatically encrypts locally and for decryption in my case you need a password and a key file.

Generally speaking, you should always test whether you can restore data from a backup. No matter which tool you use. Only then you have a real backup. And an up-to-date backup should always additionally be stored off-site (cloud, at a friend's or relative's house, etc.). Because if the house burns down, the external hard drive with the backups next to the computer is not much use.

By the way, I would advise against using just rsync because, as the name suggests, rsync only synchronizes, so you don't have multiple versions of a file. Which can be useful if you only notice later that a file has become defective at some point.

Borg Backup (specifically using Vorta front end)

Kopia repo on a separate disk dedicated to backups. Have Kopia on my servers as well sending to my local s3 gateway and second copy to wasabi.

+1 rsync, to an external harddrive. Superfast. Useful also in case I need a backup of a single file that I changed or deleted by mistake. Work files are also backed up to the cloud on mega.nz, which is very useful also for cross-computer sync. But I don't trust personal files to the cloud.

My local backups are handled by rdiff-backup to a mirror set of disks. That means my data is versioned but easily accessible for immediate restore, and now on three disks (my SSD, and two rotating rust drives). It also makes restores as simple as copying a file if I want the latest version, or an easy command if I want an older version. And testing backups is as easy as a diff command to compare the backup version with the live version.

Having your files just be files in your backup solution is very handy. At work I don't mind having to use an application like Veeam, because I'm being paid to do that. At home I want to see my backups quickly and easily, because I'd rather be working on my files than wrestling with backup software...

Remote backups are handled by SpiderOak, who have been fine for me for almost a decade. I also use them to synchronise my desktop and laptop computer. On my desktop SpiderOak also backs up some files in an archive area on the rotating rust mirror set - stuff that's large and I don't access often, so don't need to put on my laptop but do want backed up.

I also have a USB thumbdrive that's encrypted and used when I'm travelling to back up changes on my laptop via a simple rsync copy - just in case I have limited internet access and SpiderOak can't do its thing...

I did also have a NAS in the mix once, but I realised that it was a waste of energy - both mine and electricity. In normal circumstances my data is on 5 locations (desktop SSD, laptop SSD, desktop mirror set, SpiderOak's storage) and in the very worst case it's in two locations (laptop SSD, USB thumbdrive). Rdiff-backup to the NAS was simply overkill once I'd added the local mirror set into my desktop, so I retired it.

I'd added the local mirror set because I was working with large files - data sets and VM images - and backups over the network to the NAS were taking an age. A local set of cheap disks in my desktop tower was faster and yet still fairly cheap.

Here's my advice for your consideration:

• Simple is better than complicated.
• How you restore is more important than how you backup; perform test restores regularly.
• Performance matters; backups that take ages are backups you won't run.
• Look to meet the 3-2-1 criteria; 3 copies, on 2 different storage systems, with at least 1 in a different geographic location. Cloud storage helps with this.

Good luck with your backup strategy!

Restic and borg are the best I’ve tried for remote, encrypted backups.

I personally use Restic for my remote backups and rsync for my local.

Restic beats out borg for me because there are a lot more compatible storage options.

At work/for business, you can't beat Veeam. It's the gold standard and there is literally nothing better.

At home, Duplicity. Set it up once and then just let it go, and it supports a million different backup targets you can ship your backups off to, including the local filesystem. Has auto-aging/removal rules, easy restores, incrementals, etc. Encrypts by default too.

External harddrive, drag&drop.

Rsync

I almost never see rdiff-backup in such threads, so I am bringing it up now. Somehow I really like how it works and provides incremental backup with folder structures and file access still accessible directly. Works well enough for me.

Git for projects, NAS for 3D printing stuff, mods for games and unofficial game translations, Google Photos for photos (looking to migrate away from that when I have time). I don't much care about anything else.

Only syncthing, for me.

I do 2 backups

Veeam system image daily; this is a fully bootable image of every drive on my system, kept for things like hardware failure or "oops" moments. It just goes to my NAS for fast local storage.

Online backup of important files daily; this has changed a few times, I was using Restic to B2, then Duplicati to Wasabi S3, now I'm using iDrive to see how that is.

My favorite tools are definitely Veeam and Duplicati, because they both have a good UI and are easy to use, both automatically run in the background and handle scheduling entirely on their own. Browsing snapshots is easy and finding the files you want at a specific date/time is quick.

Restic and Kopia I've used as well, they're much harder to use especially for restores, finding files is a nightmare via CLI. Scheduling is a pretty involved step, and you have to figure out how to run them in the background yourself. Both also performed really slowly for me on my ~3TB backup set of about 50k files, compared to Veeam and Duplicati which are very fast.

I like Pika Backup. It's a frontend for borgbackup that also let's you mount and browse your archive with a few clicks. I think it's pretty handy on a desktop PC. And since it uses borgbackup you also get encryption with it.

KDE user so for my personal files I backup with both Kups and Bups (install both) and you get the choice of cloning type or only changed files with going back in time choices. Integrates into KDE taskbar/system settings.

For redundancy, I back up my main sync folder on the desktop to my laptop using Syncthing over my WiFi/network.

Duplicacy

grsync, its easy to use

I almost never see FreeFileSync mentioned in those threads. It's the only GUI based app I know that also gives you options to not copy file deletions for example. Also has the option to be automated with crontab. Backups are not fragmented or repackaged so you can browse them just fine. Encryption can be done with Veracrypt.

Borg backup (via Pika Backup (Libadwaita gnome app) frontend) to one of my physical drive and also to borgbase.com (free tier 10 gb free)

Simply rsync in a crontab.

I use timeshift for local backups, then duplicati for backing up to Amazon glacier monthly.

GNOME Disk Utility for backing up the whole hard drive. Otherwise, I use BackInTime.

Borg backup

I use dirvish a text based cron enabled rsync front end. Read dirvish.org for details about it.

I use this to clone and hold time based backups to external disks which I can verify or use offsite.

Rock solid for years.

I use boring old zfs snapshot + zfs send -i.
It's not pretty, but it's reliable.

I’ve recently started using proxmox -backup-client. Works well. Goes to my backup server along with my vm image backups. Works nicely with full deducing and such. Quite good savings if you are backing up multiple machines.

I the. Rsync this up to cloud once a day.

If only restic deduplicated... But other than that it does okay.

Time shift with rsync, and on occasion I clonezilla the drive and save it to my NAS.

I use back in time. It's served me well for quite a few years.
