Evaluating costs for Cloud Storage backups

[Gandalf]

Hi,
I'm trying to evaluate costs for my customers, adding a cloud storage destination to their Syncovery backups.

Depending on the storage provider, the costs can be due to the storage dimension (fixed or used space related), to the traffic, but also to a serie of other functions or commands used.
Several of these costs are well masked or hidden.
One of my actual candidates is BackBlaze B2, perfectly supported by Syncovery (I'm trying it with a free trial account).
Somewhere, in their documentation, they refer to added costs related to the number of some file operations as listing them, checking them and so on.

I don't ask for a specific evaluation but I'd like to understand if there are general settings for Syncovery, to reduce the actions that risk to be billed from storage providers.

Tank you in advance
Gandalf

Hello Gandalf,
in general, the costs for listing folders on B2 are very low. They could be relevant if you run a Syncovery job 1000x times per day and let it scan millions of files every time. So that is definitely something to avoid.

You can use the option "Cache Destination File List" under "Special" in the Syncovery profiles to avoid scanning the folders every time the job runs. This can avoid costs and speed up the process. But it is only necessary if you run the job more than once per day, or if you observe that the scanning takes a long time.

BackBlaze specify lhe list of free operations and what other is charged.
I think it is directly related to the way the API is used to transfer files.
If you agree, have you the time to verify if any of the pay sections transactions are used by Syncovery?
Just to calculate real costs for my customers ...
Thanks in advance
Gandalf
