I tested restoring by extracting the compressed, custom-format backup to a plain text SQL script1. This is much faster than restoring to DB, while still testing whether the archive is valid. For the most recent backup, I also tested restoring it on my local machine, which takes ~50 min2. (Backing up takes ~25 min3.)

Note that the compressed format is 9x smaller than plain text: 7.5 GB for all backups vs. 67.5 GB (75 GB - 7.5 GB after all were extracted)
