Honestly don't know if I'd be able to wrap my head around the spec even if it was released haha. Me seems like it is a good candidate for a tertiary backupĪlso, if it matters to you, the spec is not posted. I spent a while helping you, a random internet stranger, and it is very uncool to have me waste that. Whether it is enough is up to you.Įdit2: I am taking your work that you are not, as the other guy alleges, related to the developer of BlobBackup. And I don't mind paying for the software I use (I am a "sponsor" of rclone on github for that exact reason)Įdit: I am leaving my comment as it was for posterity but looking at the BlobBackup site, it seems as though the default chunk was increased to 1mb and there is a bit more detail about how it works. I am cautious, especially with backups, but not unwilling. With that said, I am always willing to consider new tools. I also use it for a lot of other things so I feel completely comfortable with its quirks. That means that recover is way easier and, if I don't use encryption, I am not relegated to a special tool. But there is a major upside: Each file is 1:1 (or 1:encrypted-1) on B2. And multi-machine support doesn't exists either. There is basically no way, whatsoever, that it is the most storage efficient. with crypt where you have to rely on size). It has no deduplication and rudimentary move tracking (esp. I spent a lot of time thinking about these backup tools and I've landed on good old rclone with -backup-dir and/or B2's LifeCycle rules. But does the developer of BlobBackup know? And has (s)he accounted for them?) (but here again, I know restic has concerns about some security issue using compression with encryption. Then again, I do not know what they are doing with compression. There are some very good reasons to use fixed-length chunks but, in general, you'd expect it's overall efficiency to be lower. I am very surprised you got the best size reduction with BlobBackup as it has fixed-length chunks (blobs). I am not sure how the others do it but also, I think they use larger chunks. Duplicacy talks about how they use the same chunker to break that up. Also, one issue that all of these chunk-based tools have is that as the blobs get smaller, the database grows! (for example, a 2 gb file will have 8192 blobs at the default chunk size of 256kb for BlobBackup. Or people who are experts to at least weight in. That may or may not be a deal breaker but when it comes to encryption and recoverability, you want to know more about it. Also, if it matters to you, the spec is not posted. That to me seems like it is a good candidate for a tertiary backup. Has anyone else tried it yet? Wanted to get some thoughts before i commitīlobBackup is very new and feels, at least from the site, to still be in active development. So far BlobBackup is looking like the clear winner for me. good support and very active developerĬons: no vss on Windows. restore didnt work properly for me even once. Pros: free and open source (honestly thats it)Ĭons: super slow. 49.99 USD/computer one time purchaseĬons: slow. lots of features (cpu usage, wifi selection, vss). 50 USD/computer/year is quite expensive for my business data considering the alternatives active fourmsĬons: clunky ui (feels unfinished honestly). Kopia seems to be as fast or faster than Duplicacy, with a significant advantage in size, and also number of file chunks created (88 files in kopia repo vs 1822 in duplicacy repo).Transitioning from backblaze personal to B2 with a separate client because I needed more control and speed. It was run on a Debian 11 VM, 16GB RAM, 12 CPU in VMWare Workstation. This was not a rigorous benchmark, just a quick test. Settings: Kopia: parallel=12, compression=zstd Here are the elapsed real times (in seconds) as reported by the time command, with the user CPU times and system CPU times in the parentheses:Ĩ35M /benchmark/test/linux-duplicacy-storageĢ.2G /benchmark/test/linux-restic-storage Here is a comparison (benchmark) based on Results (linux kernel):
