Switched to BorgBackup

The old joke says that there are two types of people:

I was in second group long time ago and then moved to first one.


So far I used Duplicity along with it’s fronted called Duply. It was installed by default on Ubuntu systems and was quite easy to setup.

But getting files restored from it was pain. And consistency was a problem. Especially when I wanted to restore one directory from quite old copy — turned out that one file (of many) was damaged so whole backup was useless…


So I looked for alternatives and BorgBackup was one of suggestions.

Features list was long, FOSS, several platforms, compression etc. There were two things which brought my attention:


So why deduplication? Because it allows me to backup several machines into one place and separate copies of git repositories, source code will not take extra space:

                       Original size      Compressed size    Deduplicated size
All archives:                2.02 TB              1.57 TB            118.85 GB
                       Unique chunks         Total chunks
Chunk index:                 1060634             18670536

Or on my server where backups are run hourly:

                       Original size      Compressed size    Deduplicated size
All archives:                7.29 TB              5.36 TB             11.35 GB
                       Unique chunks         Total chunks
Chunk index:                  359783            260310747

Nice difference compared to Duplicity I used before.

FUSE mounting of backups

Instead of checking which options I have to use to restore that one directory from 2 months old backup I can now mount each backup using FUSE:

borgmatic mount --archive puchatek-2021-01-01 --mount-point /tmp/del/1

And then just copy whatever file(s) I want to restore. Very handy way.


What Duply was to Duplicity, Borgmatic is to BorgBackup. Simple, easy to use frontend hiding most of internals behind easy to use command line interface.

Configure once, then simple commands like “borgmatic info”, “borgmatic prune” etc. All needed things are stored in config file.

Will it work for me?

Time will show does it work for me. Machines’ backup copies are done, syncing them between machines need some improvements.
