Sharing a Backup

Scenarios

You can share server or disk backups with projects of other accounts. Shared backups can be used to create servers or disks.

Context

For sharers:

• Backups can only be shared among projects of accounts in the same region. They cannot be shared across regions.
• When a sharer deletes a shared backup, the backup will also be deleted from the recipient's account, but the disks or servers previously created using the backup will be retained.

For recipients:

• A recipient must have at least one backup vault to store the accepted shared backup, and the vault's remaining space must be greater than the size of the backup to be accepted.
• A recipient can choose to accept or reject a backup sharing request. After accepting the backup, the recipient can use the backup to create servers or disks.
• When a sharer deletes a shared backup, the backup will also be deleted from the recipient's account, but the disks or servers previously created using the backup will be retained.
