If you want an immutable backup where you can't delete data from the backup, you can look into using borgbackup with the -append-only flag set at creation (see here: ). However, tape drives and media are expensive for larger capacities (even used) since you'd need an auto loader so backups won't be a total pain in the butt. You could also back up to tape and then set the tape as read only via the switch (). I guess that all depends on your definition of "immutable." You could burn your backups to CD/DVD/Bluray and have it read only, but that's going to cost a bit and the storage space would be exponential as your data grew. But, as far as I can tell, Veeam is tailored specifically for cloud services rather than for personal computers, as well as needing a complex set-up, so it's unsuitable. I found the heavily-advertised Veeam (), which seems reasonably priced. I'd find it too complex to have to start setting up servers and whatnot it needs to be reasonably straightforward. Obviously, I'd like a solution for Ubuntu, but if it were also available for Windows and Mac (so that I could recommend it to non-Linux users), that would be great.Īnother factor would be ease of use. Both provide incremental backups, but neither provides an immutable option. In a world where ransomware has become clever enough to mess with backups, I was wondering how to create incremental backups, but make each increment immutable?Īt the moment, I use two daily backup solutions: SpiderOakONE () for online (off-site) backups, and rdiff-backup () for offline (on-site) backups.
