Release compatibility for incremental backups and restores

After you upgrade your system, you can extend backup sets from the earlier release with incremental backups from the newer release. You can restore the backups and incrementals to the later release. However, if you downgrade to the previous release, keep in mind the following restrictions:

• You cannot add increments to a backup set that was created on, or last incremented by, a later Netezza Performance Server release.
• You cannot restore backups or increments that are created by a later release. For example, assume that you have backup sets that are created on the earlier release, and following an upgrade, you add increments from the later release. If you downgrade to the earlier release, you can restore the backups and increments that are created on that earlier release, but you cannot restore any increments that are created with the later release.
