The backup process for Google Cloud Platform is comprised of different stages depending upon the type of backup operation.
Streaming Backup
A streaming backup operation for Google Cloud Platform includes the following stages:
-
Create snapshots of all disks that are associated with the source instance.
The snapshots are created in the source instance project.
-
Create disks from the snapshots.
For environments with multiple projects, the disks are created in the project that is associated with the access node.
-
Delete the snapshots that were created in stage 1.
-
Attach the created disks to the access node.
-
Populate the config file, and then save it.
-
Read each attached disk, and back up the disk data.
-
Delete the disks that were created as part of the backup process.
Streaming Backup with Encryption
A streaming encrypted backup operation for Google Cloud Platform includes the following stages:
-
Verify support of the encrypted disk.
If the encryption type is not supported, the disk is filtered out.
-
Create encrypted snapshots for disks in the source instance project.
-
If the access node and instance are in different projects:
-
Create unencrypted disks from encrypted snaps in the source project.
-
Create unencrypted snap from unencrypted disk in the source project.
-
-
Create unencrypted disks from encrypted snaps in the Google Cloud project.
-
Attach the created disks to the access node.
-
Populate the config file, and then save it.
-
Read each attached disk, and back up the disk data.
-
Delete the snaps and disks that were created as part of the backup process.
IntelliSnap Backup
- Create a snapshot in the source instance zone.
IntelliSnap Backup Copy
Creating an IntelliSnap backup copy includes the following stages:
-
Create a snapshot in the source instance zone.
-
Create a disk from the IntelliSnap backup snapshot.
If there were multiple projects in the environment, IntelliSnap creates the disk in the project associated with the access node.
-
Attach the disk to access node.
-
Read each attached disk, and then backup the disk data.
-
Delete the disk you created in stage 1.
