My dear lemmings,
I discovered Clonezilla a while ago and it still is my main tool to backup and restore the partitions I care about on my computers.
I cannot help but wonder if there are now better, more efficient alternatives or is it still a solid choice? There’s nothing wrong with it, I’m just curious about others’ practices and habits — and if there was newer tools or solutions available.
Thank you for your feedback, and keep your drives safe!
The main thing about Clonezilla is that you can always rely on it working, no matter the system. The bad thing is that proprietary solutions have a lot more creature comforts.
The fact that Linux lacks a decent system-level backup tool with a GUI is kind of a mind boggler for me. The best one I’ve found which gets close to this is timeshift. File-level backups can’t restore your whole system state and users shouldn’t be expected to remember or manually export their package lists and god knows what else. I have subsisted on file-only backups but it’s really not great as a solution. Disks fail, and when they do, you inevitably have to reinstall the entire OS. It’s a mess. RAID1 could theoretically prevent this, but no distro makes it easy to boot from a RAID1 setup.
Backing up the entire filesystem is not a technically complex thing, there are plenty of command-line tools to do this and some filesystems even support this concept via snapshots etc. But this has yet to be put into a useful practice for end users.
There is btrfs-assistant, for example.
with a GUI
Look for one without a GUI and learn its command-line, and you’re done.
Second for Rescuezilla, it’s a Clonezilla front end with sane defaults you’d probably pick anyways.
I use clonezilla at work for imaging and deploying laptops. It works like a charm. Great piece of software. It’s not normal backup software though.
Rescuezilla is nice. I believe it just puts a more user friendly GUI on clonezilla
Clonezilla has its place, but not as a main backup and restoration tool. I personally don’t see it as a backup tool, especially that it operates at partition level for such. What you want is you base install system and file level backups for your data (/home/) etc. For the file level backups, use something like restic. Backup what you need to go from a fresh install to a system with your data back on it. Packages can be reinstalled.
Restic is my primary backup for all my devices. If I need something more than fresh iso -> my data system, I use packer.
I noticed for file level backups you mentioned something other than rsync. Any particular reason why you landed on restic instead?
Because that serve different purposes. rsync is for moving data around, synchronization of such. It has no concept of point in time restoration, or snapshots (etc) that really define a backup solution. I use restic because its the proper tool for the job.
point in time restoration, or snapshots
Do you mean like not just having another copy of a file, but being able to restore a specific version of a file?
There’s a lot more going on with restic aside from just that, but yes. So with an rsync of your home dir (for example), it’s reliant on the FS to do compression and deduplication (ZFS,btrs), and/or it will still take up a lot of wasted space. Say you got ransom-wared. It’s okay you have that rsync backup, but oh crap it got ransom-wared to. No more backups to try? Restic gives you snapshots for whatever increment you set and just handles it simply. You can then restore one file from any of the snaphots (history) or every single file. Restoreing 250kb vs 400TB is quite a difference. The benefits of this, are huge even beyond the fire and forget capability.
I mean, rsync handling everything via mirroring and pushed to a ZFS FS, would be sort of the same thing.
The big advantage of Clonezilla or using dd is you make a perfect 1:1 copy of the disk so you’re pretty confident it will restore perfectly, but you need a disk of at least the same size and so on. Also perfect if you’re trying to do file recovery and so on, because even corrupted or entirely unreachable data is still technically on the disk.
That’s very inefficient when you have say, 5GB used of a 1TB disk, although compression will help a bit. But that’s where more specialized tools comes in: what if we could only backup the actual data, and end up with a 5GB backup before compression.
That’s useful and nice, but can’t possibly deal with corrupted or deleted files since it’ll just skip over them. The backup is only as good as all the filesystem features the archiver can encode. On Linux, tar has us pretty well covered as long as you only need relatively standard features like owners, groups. If you zip your root Linux partition you’ll end up with broken ownership and permissions, because it doesn’t encode ACLs and xattrs and hardlinks and whatever else. On NTFS, since it’s proprietary, undocumented and a fairly complex filesystem, it’s much riskier. If you backup your game library, you’re probably fine, but if you want Windows to boot after a restore, you need a much more complete backup and if you don’t want to take risks, whole partition backups are much safer. ntfsclone exists but I just don’t trust it like I would trust tar to backup my ext4 partitions correctly.
So it’s all a tradeoff. Do you want efficiency, or do you want reliability? How much of the information can you lose? Like, if you backup your C: drive on Windows but only care about your files and documents but not the Windows install itself, then it makes sense to just archive the files rather than a block copy.
So, what do you expect from your backups? The answer to that question also answers this thread.
That’s correct for dd but not for clonezilla.
Clonezilla uses partclone, which reads the file system and copies only the data, for any filesystem sorted by partclone.
I have never gotten Clonezilla to work. I don’t want to call it obsolete, but… it certainly isn’t intuitive, and in 2024 I expect even open source software as widely known as Clonezilla to have a straightforward interface.
For simple data backups, I use Kopia.
EDIT: Apparently there’s a GUI for Clonezilla called Rescuezilla. I’ll have to give it a try sometime.
Somewhat curious how CZ has never worked for you. I’ve used it for years and any failures it has had were fixed with tweaking some of the options. I love the tool myself, but I have also never heard of Rescuezilla so thanks for that. I think I’ll give that a go next time.
It’s been a while since I tried it, so I don’t recall exactly what didn’t work the last time. I think it may have been driver related.
I’m definitely going to give it another go one of these days.
