hi,
i use a combo of wasabi for recent backups and aws deep glacier for older backups.
in all my testing and based on forum posts,
nothing comes close to wasabi in terms of the number of api calls per second.
wasabi does not charge for api calls.
i have a folder with over 1,000,000 files in it, and need to sync it daily so not being charged for api charges is a major deal.
and rclone can sync that in approx. 40 seconds, assuming no files need to be uploaded.
that is correct but there are hard limits, and if you hit those limits wasabi can/will cancel your account.
the major downside is that wasabi has a minimum retention period of 90 or 30 days.
so if you upload a 1TB file today, delete it tomorrow, wasabi will charge you for 89 additional days.
note: the default retention policy is 90 days but if you upload veeam backup files, like i do,
you can contact wasabi and they will reduce the retention period to 30 days, for all files, not just veeam files.
very easy to saturate a 1Gbps internet connection.but that can apply to other cloud providers.
one advantage of wasabi, is that it is s3 compatible, up to a point.
so aws and wasabi, both have iam polices, can require MFA tokens before files can be deleted, object locks.
also, client side encryption using sse-c in cases where rclone crypt is not acceptable.
i have python script that makes use of those features.
