Make disk image with zoolz12/27/2023 ![]() Not only does it give you peace of mind that the backups are doing their job and are viable, but that YOU know how to do a restore if one is needed. And remember, while a process like How to test / verify your backups is good, NOTHING beats an occasional actual restore and file comparison. My best suggestion would apply to ANY backup tool (including Duplicati) - just make sure you TEST your backups from time to time. That being said, what I’ve noticed is for any particular installation it either seems to work really well (for most users) or terribly (for very few users) - in both cases pretty consistently. Last month (May 2018) there were 124 new topics created on this forum (including How-To guides, Release notifications, etc.) while the following backup counts across all versions of Duplicati (including bleeding edge canary versions) were logged (for installations where usage reporting has NOT been disabled):įor me, that low of a reporting rate for that high of a usage implies this is pretty safe software. While a forum isn’t necessarily the best place to get an impression of software (because most of what you see are users reporting issues) consider this. For something in “beta” it is VERY stable. I personally use the most recent canary (alpha) versions MOSTLY without issue (just stay away from 2.0.3.6 and 2.0.3.7).įor my clients I use the most recent beta version without issue.ĭuplicati 2 has been in beta for a long time (not quite Gmail beta long, but longer than many applications). Again, Duplicati CAN back them up, but because of how encryption often works a single change to a file will cause the entire file to be re-encrypted which pretty much defeats the de-duplication feature of Duplicati. If you think of a virtual disk image running Windows, imagine all the temp files Windows generates - if you’re backing up the image, you’re backing up ALL those temp files where if you run Duplicati inside the virtual machine it can be configured to ignore temp files. (Note that Windows support for USN based backups is being worked on, which could eliminate this issue on that OS and open up potential support for Linux & MacOS.)Īdditionally, while you CAN back up virtual disk images with Duplicati, because of how they work you’ll likely get much better results running Duplicati IN the virtual machine than backing up the virtual disk. So most likely more time will be spent scanning files for changes than actually backing anything up. This is because boot sectors and things like that are NOT files seen by the OS, so Duplicati doesn’t back them up.Įverything else I can think of are general suggestions - for example, very frequent job runs (like every 5 minutes) probably won’t benefit you right now because (by default) that means Duplicati will scan ALL your source files every five minutes. Even if you configure Duplicati to back up your entire boot drive and restore it to another drive, you will NOT be able to boot off the restored drive. So the one thing - Duplicati is a FILE level backup tool, NOT a block level drive imager. What NOT to do with Duplicati 2 right now?Īs far as things “not to do” with Duplicati, I can think of one thing people often try to do and the rest are more usage guidelines than “don’t do this or it will break” type directives. If you look at the Duplicati GitHub issues page you’ll see reported issues (such as temp folder not being cleaned up in 2.0.3.6 and 2.0.3.7) as well as feature requests (such as adding “Zoolz” destination support). ![]() If you look at the # bug tags on the forum here you’ll see specific items some people have reported that have been verified as not working correctly. It works, but turns out to be SLOWER than the old code. Duplicati beta versions tend to be VERY stable, however canary versions are more bleeding “alpha” type releases.įor example, in versions 2.0.3.5 and 2.0.3.6 (both canary “alpha” versions) more multi-threaded processing was added. The answers depend partially on what version of Duplicati you are using and what you consider to be “not working”.įor example, doing a 2.0.3.3 beta bug search shows it currently having only one reported “bug” (which is actually just a display problem in the user interface). You’ve asked some important questions there - thanks for thinking of them!
