I’m considering Restic and Backblaze B2 as my backup solution. I’m a little worried having read about the potential for unexpected restore costs. For example, I’ve read restoring lots of little files adds to the cost (reference). What are the things to look out for when backing up and restoring that can add to the cost? Are there any best practices to keep costs down?

    I use B2 for my restic Backup. Currently i have about 100GB stored there and it says i have about 100,000 files stored.

    With the adjusted calculation of the blog you posted for 10TB of 50KB files, adjusted to the mean file size of my restic repository 10 TB of 1MB files:

    Transaction fees: 10,000,000 / 10,000 x $0.004 = $4

    My Laptop has a mean file size of about 16 MB per file on the local restic repository.

    EDIT: Forgot a resume, i do not think you need to worry about it too much. But maybe verify the amount and type of data you want to backup and use calculators to calculate the real cost, also you can always test it by creating a test dataset and then do a backup and recovery scenario and then use this to derive an estimate.
