Backup tool evaluation

(Update 2021-10-17: Read about the final decision here)

Because now I need backup.

Tools considered:

• duplicati
• duplicity
• borgbackup
• restic

Not considered:

• arq - Mac/Win only, not free
• bacula - waaay to complicated, apparently no S3 support
• bup - no s3 support
• bupstash - self-called alpha software, no S3 support
• clonezilla - no S3 support, only block device backups
• duplicacy - only free for non-commercial use

Links:

• a user’s performance comparison
• encrypted backup shootout
• Duplicacy: A lock-free deduplication cloud backup tool (nice comparison as well)
