You can create and configure SnapMirror unified data protection relationships to configure disaster recovery and archiving on the same destination volume.

What you’ll need

You must be aware of the considerations for creating unified data protection relationships for FlexGroup volumes.

Considerations for creating a SnapVault backup relationship and a unified data protection relationship for FlexGroup volumes

Steps

Create a destination FlexGroup volume of type DP that has the same number of constituents as that of the source FlexGroup volume:

From the source cluster, determine the number of constituents in the source FlexGroup volume: volume show -volume volume_name* -is-constituent true

cluster1::> volume show  -volume srcFG* -is-constituent true
Vserver   Volume         Aggregate    State      Type       Size  Available  Used%
--------- ------------   ------------ ---------- ---- ----------  ---------- -----
vss       srcFG          -            online     RW         400TB   172.86GB  56%
vss       srcFG__0001    Aggr_cmode   online     RW         25GB    10.86TB   56%
vss       srcFG__0002    aggr1        online     RW         25TB    10.86TB   56%

From the destination cluster, create a destination FlexGroup volume of type DP with the same number of constituents as that of the source FlexGroup volume.

cluster2::> volume create -vserver vsd -aggr-list aggr1,aggr2 -aggr-list-multiplier 8 -size 400TB -type DP dstFG

Warning: The FlexGroup volume "dstFG" will be created with the following number of constituents of size 25TB: 16.

From the destination cluster, verify the number of constituents in the destination FlexGroup volume: volume show -volume volume_name* -is-constituent true

cluster2::> volume show  -volume dstFG* -is-constituent true

Create a job schedule: job schedule cron create -name job_name -month month -dayofweek day_of_week -day day_of_month -hour hour -minute minute

For the -month, -dayofweek, and -hour options, you can specify all to run the job every month, every day of the week, and every hour, respectively.

The following example creates a job schedule named my_weekly that runs on Saturdays at 3:00 a.m.:
```
cluster1::> job schedule cron create -name my_weekly -dayofweek "Saturday" -hour 3 -minute 0
```
Create a custom policy of type mirror-vault, and then define a rule for the mirror and vault policy:
1. Create a custom policy of type mirror-vault for the unified data protection relationship: snapmirror policy create -vserver svm_name -policy policy_name -type mirror-vault
2. Define a rule for the mirror and vault policy that determines which Snapshot copies are transferred during initialization and update operations: snapmirror policy add-rule -vserver svm_name -policy policy_for_rule - snapmirror-label snapmirror-label -keep retention_count -schedule schedule
If you do not specify a custom policy, the MirrorAndVault policy is used for unified data protection relationships.
Create a unified data protection relationship: snapmirror create -source-path src_svm:src_flexgroup -destination-path dest_svm:dest_flexgroup -type XDP -schedule schedule_name -policy MirrorAndVault
```
cluster2::> snapmirror create -source-path vss:srcFG -destination-path vsd:dstFG -type XDP -schedule Daily -policy MirrorAndVault
```
From the destination cluster, initialize the unified data protection relationship by performing a baseline transfer: snapmirror initialize -destination-path dest_svm:dest_flexgroup
```
cluster2::> snapmirror initialize -destination-path vsd:dstFG
Operation is queued: snapmirror initialize of destination "vsd:dstFG".
```
