Storage Checkpoints can only be used to restore from logical errors (for example,
a human error). Because all the data blocks are on the same physical device, Storage
Checkpoints cannot be used to restore files due to a media failure. A media failure
requires a database restore from a tape backup or a copy of the database files kept
on a separate medium. The combination of data redundancy (disk mirroring) and
Storage Checkpoints is recommended for highly critical data to protect them from
both physical media failure and logical errors.
Backing up using a Storage Checkpoint
You can back up a database by creating a Storage Checkpoint using the
dbed_ckptcreate command, mount the Storage Checkpoint as read-only using
the dbed_ckptmount command, and then back it up using tools such as tar or
cpio.
