[QUOTE="klepto, post: 1064431, member: 87970"] Testing an interesting offline backup solution for long term storage called bup. It has some glorious features, such as: [LIST] [*]It uses a rolling checksum algorithm (similar to rsync) to split large files into chunks. The most useful result of this is you can backup huge virtual machine (VM) disk images, databases, and XML files incrementally, even though they're typically all in one huge file, and not use tons of disk space for multiple versions. [*]It uses the packfile format from git (the open source version control system), so you can access the stored data even if you don't like bup's user interface. [*]Unlike git, it writes packfiles [I]directly[/I] (instead of having a separate garbage collection / repacking stage) so it's fast even with gratuitously huge amounts of data. bup's improved index formats also allow you to track far more filenames than git (millions) and keep track of far more objects (hundreds or thousands of gigabytes). [*][I][B][B][I]Bup can use "par2" redundancy to recover corrupted backups even if your disk has undetected bad sectors.[/I][/B][/B][/I] [*]Even when a backup is incremental, you don't have to worry about restoring the full backup, then each of the incrementals in turn; an incremental backup [I]acts[/I] as if it's a full backup, it just takes less disk space. [*]You can mount your bup repository as a FUSE filesystem and access the content that way, and even export it over Samba. [/LIST] Bup has a fsck feature with par2 built in and par2 has recovered a ton of stuff for me in the past that I thought was not retrievable.. 🏴☠️🏴☠️🏴☠️ I already use vorta(borg) and restic along with a NAS box but this will be able to be put anywhere and easily accessed. It also has gui options for those who don't like in the terminal like I do. [/QUOTE]
