I’m switching from Backblaze B2 to Scaleway’s Object Storage. I used to use B2 as a backup destination for my restic backups from various servers.

Under the hood the volumerize image is using the GNU program duplicity, which is an awesome software, but also has its downsides. Especially the model of full backups and incremental backups comes from a time where backups where mainly made to tapes (just append new files all the time).
