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 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.
