Snapshots can quickly consume storage space, especially if multiple snapshots are taken.
Snapshots may not capture all changes if there are active processes or open files during the snapshot creation.
Snapshots are not a substitute for regular backups and should not be relied upon as the sole backup solution.

Q91. What is Thin vs thick provisioning ?
Thin provisioning allocates storage space on demand, while thick provisioning allocates all space upfront.
Thin provisioning only allocates storage space as it is needed, reducing wasted space
Thick provisioning allocates all storage space upfront, regardless of actual usage
Thin provisioning is more flexible and efficient, but can lead to over-allocation if not managed properly
Thick provisioning provides better performance but may result in wasted space
Example: Thin provisionin...read more
