Size Mismatch Between MSP Space Used and Amazon AWS Alternative approach:
We do not allow deletion of storage at the client MSP360 console as a hacker can delete your backups when installing ransomware. It is a setting in the Advanced Branding. It actually happened to one of our clients - the hacker installed ransomware and deleted backups, but fortunately they failed to remove all THREE of our backup copies (One Local, two cloud). After dodging that howitzer, we disabled deleteion of backups from the console and instead use Cloudberry Explorer (or the Backblaze Portal), then we run a repository sync on the client to update the storage usage.
Yes the repository syncs take a long time, and unfortunately no backups can run until repo syncs are complete.
It would be great to separate the repo syncs such that for example, we could still run a local backup while the Amazon repository sync is in process.
And if all that seems like too much trouble, and you want to use the console to delete backups as David suggest, please be sure that you have an MBS console password set , including CLI, and that it is different than the server password.
