Abstract: One embodiment is related to a method for automatically removing a mount point, comprising: determining whether a vMotion live migration has been completed for a virtual machine (VM) recovered through Instant Access from a backup storage system; after the vMotion live migration has been completed, determining whether a datastore corresponding to a backup image of the VM on the backup storage system is empty; in response to determining that the datastore corresponding to the backup image of the VM on the backup storage system is empty, removing automatically a mount point corresponding to the datastore; and after removing the mount point, freeing up storage space on the backup storage system corresponding to the datastore.

Abstract: Backing up files storing virtual machines is described. A system identifies a file storing multiple virtual machines. The system creates a backup of the file. The system identifies a failure of the file. The system restores the multiple virtual machines based on the backup of the file.

Abstract: Handling backups when target storage is unavailable is described. A system determines whether the target storage is unavailable for storing any backup file for a client. The system determines whether a backup file is created for the client if the target storage is unavailable for storing any backup file for the client. The system stores the backup file in a memory of a computer if the backup file is created for the client, wherein the computer differs from the target storage and differs from the client. The system determines whether the target storage is available for storing the backup file for the client. The system transfers the backup file from the memory of the computer to the target storage if the target storage is available for storing the backup file for the client.
