Which storage class do you recommend that I use?
Please ensure you have read through the Google documentation on storage classes here: https://cloud.google.com/storage/docs/storage-classes
Ultimately, the best storage class for your situation depends on how often you intend to access the data in storage.
CloudM Backup accesses data in cloud storage in the following scenarios:
- Backup operations
- Restore operations
- Purge operations
Generally, we recommend that a customer use either standard storage or nearline storage. The choice between these two depends on how often you expect to perform the above operations. Nearline storage costs can be as much as 3x cheaper than standard storage (depending on region). However, charges apply whenever data is accessed.
We recommend that you use the Google Cloud Storage price calculator here: https://cloud.google.com/products/calculator
Will CloudM Backup cause any additional charges to be applied to my Google Cloud Storage account?
For a full overview of how Google Cloud Storage pricing works, please see their official documentation: https://cloud.google.com/storage/pricing
Data storage and data retrieval costs are covered in the answer above and completely rely on the storage class you intend to use and how much data you intend to store.
Network costs occur whenever data is read from cloud storage, also known as egress. Egress charges from Google Cloud Storage should be minimal unless restoring very large amounts of data per month. A full egress pricing breakdown can be seen here: https://cloud.google.com/storage/pricing#network-egress
Operations costs may occur as CloudM Backup does use some class A and class B operations. However each GCS account has a free quota of operations per month and the amount of operations used by CloudM Backup depends entirely on how the product is used.
Below is a breakdown of all of the class A and class B operations used by CloudM Backup:
Class A
storage.*.insert | Twice per item migrated when backing up a user |
storage.*.patch | Twice per item migrated when backing up a user |
storage.*.update | Twice per item migrated when backing up a user |
storage.objects.list | Once per user or once per restore operation |
Class B
storage.*.get | Twice per item migrated when backing up a user or performing a restore |
