You can create a backup of data using Thin Image. When creating a backup from the S-VOL after storing snapshot data, the target for the backup is only the areas where the snapshot data is stored. Therefore, you can create a backup copy even if the pool capacity is small.
During creation of a backup copy, a significant amount of data is read from the secondary volume. This may increase the accesses to the primary volume and degrade the host I/O performance.
- Store the snapshot data, or clone pairs.
- Use an S-VOL.
