REPLICATION AND RESTORATION OF SINGLE-INSTANCE STORAGE POOLS
First Claim
1. A computer system comprising:
- a first storage pool; and
a second storage pool;
wherein a first backup server of the first storage pool is configured to;
convey a first de-duplicated list identifying one or more data segments from the first storage pool to a second backup server associated with the second storage pool;
receive from the second backup server a second de-duplicated list identifying at least a subset of the one or more data segments; and
convey the subset of the one or more data segments to the second storage pool.

Abstract
A system and method for managing single instance storage. A computer system includes at least two backup servers, each backup server included in a single-instance storage pool. A first backup server conveys a first de-duplicated list identifying data segments from the first storage pool to a second backup server. The first backup server receives from the second backup server a second de-duplicated list identifying a subset of the data segments and conveys the subset of the data segments to the second backup server. In response to receiving the first list from the first backup server, the second backup server de-duplicates the first list against a second storage pool and conveys the second list to the first backup server. In response to receiving the subset of the data segments, the second backup server adds the received data segments to the second storage pool.

-
conveying a first de-duplicated list identifying one or more data segments from a first storage pool to a second backup server associated with a second storage pool; receiving from the second backup server a second de-duplicated list identifying at least a subset of the one or more data segments; and conveying the at least a subset of the one or more data segments to the second backup server. - View Dependent Claims (9, 10, 11, 12, 13, 14)
