When the CloudPools version differs between the source cluster and the target PowerScale cluster, the CloudPools’ cross-version compatibility is handled.
NDMP and SyncIQ provide two types of copy or backup: shallow copy and deep copy. For more information about NDMP and SyncIQ protection, refer to the white paper High Availability and Data Protection with Dell PowerScale Scale-out NAS.
Table 1 shows the CloudPools and OneFS mapping information. CloudPools 2.0 is released along with OneFS 8.2.0. CloudPools 1.0 is running in OneFS 8.0.x or 8.1.x.
OneFS version | CloudPools version |
OneFS 8.0.x/OneFS 8.1.x | CloudPools 1.0 |
OneFS 8.2.0 or higher | CloudPools 2.0 |
Table 2 shows the NDMP and SyncIQ supported use cases when running a different version of CloudPools on the source and target clusters. As noted below, if CloudPools 2.0 is running on the source PowerScale cluster and CloudPools 1.0 is running on the target PowerScale cluster, shallow copies are not allowed.
