Managing Pure Storage Protection Groups

A Pure Storage Protection Group is a collection of volumes, hosts, or host groups protected together with point-in-time consistency. This is achieved using snapshot schedules. Members of a protection group share common retention criteria and snapshot schedules.

Protection groups use asynchronous replication, retaining snapshots locally and replicating them to target storage systems based on a predefined replication schedule. A single protection group can contain multiple volumes, hosts, or host groups, and a single volume can belong to multiple protection groups.

Creating a Protection Group

Use the purepgroup create CLI command:

usage: purepgroup create --hgrouplist HGROUPS |--hostlist HOSTS | --vollist VOLS --targetlist TARGETS PGROUP

Common arguments:

PGROUP: Protection group name
--hgrouplist HGROUPS: Host groups
--hostlist HOSTS: Hosts
--vollist VOLS: Volumes
--targetlist TARGETS: Target arrays

pureuser@FlasharrayX90> purepgroup create PG-LXPROD01 --vollist LXPROD01-0,LXPROD01-1 --targetlist FlasharrayX50

Name        Source          Targets         Host Groups     Hosts   Volumes
PG-LXPROD01 FlasharrayX90 FlasharrayX50     -               -       LXPROD01-0
                                                                    LXPROD01-1

Enabling Protection Group Features

Enable the group for snapshots or replication (or both):

usage: purepgroup enable --replicate --snap PGROUP

Possible arguments are:

PGROUP: Protection group name
--replicate: Enable replication schedule
--snap: Enable snapshot schedule

pureuser@FlasharrayX90> purepgroup enable --replicate PG-LXPROD01

Name        Schedule        Enabled Frequency       At      Blackout
PG-LXPROD01 snap            False   1h              -       -
            replicate       True    4h              -       -

Setting a Replication Schedule

Use purepgroup schedule:

common usage: purepgroup schedule --snap-frequency FREQUENCY --replicate-frequency FREQUENCY PGROUP

Common arguments:

PGROUP: Protection group name
--snap-frequency FREQUENCY: Take snapshots at this frequency. N[s/m/h/d/w] e.g. 15m, 1h, 2d, 3w
--replicate-frequency FREQUENCY: Take and replicate snapshots at this frequency. N[s/m/h/d/w] e.g. 15m, 1h, 2d, 3w

pureuser@FlasharrayX90> purepgroup schedule --replicate-frequency 30m PG-LXPROD01

Name        Schedule        Enabled Frequency       At      Blackout
PG-LXPROD01 snap            False   1h              -       -
            replicate       True    30m             -       -
