A previous post describes how I had already used Borg to deduplicate backups of my data. So even if two files were nonidentical, Borg could save space by eliminating duplication within them, if they shared chunks of identical data. It beat DoubleKiller as well as WinRAR (and Windows Imaging Format) in another way: it would deduplicate data clusters on the subfile level. Anyway, they were pointers: you wouldn’t have your full files back in original condition.īorg, a Linux tool, would save duplicate files as pointers, but it would restore the full original files. That is, if you copied them from drive E to drive D, they would still be pointing at a duplicate on drive E.

The pointers were absolute, not relative. WinRAR would apparently do better at that than DoubleKiller: a drive deduplicated using DoubleKiller would not be fully restorable. So you would still find a file with the same name (albeit a different extension) in both locations – but one would be just a small pointer to the other, full, original file, thus cutting drive space usage almost in half (or one-third, if the drive being deduplicated had three copies of the same file). Some duplicate deleters (including DoubleKiller) could go one better: they could replace duplicate files with pointers.

Deduplication could mean just deleting duplicate files. Maximum compression was therefore a good idea.ĭeduplication could help with that.

I didn’t want to have to burn any more of them than necessary. But if an electromagnetic pulse or malware ever managed to corrupt my hard disk drives (HDDs), these written-in-stone discs would be as close as I could come to a failsafe backup (unless I stored one of those HDDs in a Faraday box).īD-Rs didn’t hold a lot, and they were slow to write and slow to read. The mission at hand was to burn a fail-safe copy onto Blu-ray (BD-R) optical discs. I already had backup drives containing copies of those assorted system and drive backups. xz) backups of bootable Windows and Ubuntu USB drives. I also had a bunch of Windows and Ubuntu virtual machines (VMs, including either VirtualBox VDIs or VMware VMDKs) backed up in WinRAR’s RAR format. I had a bunch of Windows (XP, 7, 10) drive images in AOMEI’s ADI format. Nonetheless, I welcome suggestions that may help to resolve the problem and advance the project. At the moment, I was unfortunately out of time for further efforts along these lines. As indicated below, the effort stalled at the point of restoring the Windows images from Borg backup to bootable form. This post describes an effort to use Borg to shrink a set of Windows and Ubuntu drive backup images to a very small archive.
