Use "pxctl sched-policy [command] --help" for more information about a command.

Create a schedule policy

To create a snapshotting policy, use the pxctl sched-policy create command. Run it with the --help flag to list the available options:

pxctl sched-policy create --help
Create a schedule policy

Usage:
  pxctl sched-policy create [flags]

Aliases:
  create, c

Examples:
pxctl sched-policy create [flags] policy-name

Flags:
  -p, --periodic string   periodic snapshot interval in mins,k (keeps 5 by default), 0 disables all schedule snapshots
  -d, --daily strings     daily snapshot at specified hh:mm,k (keeps 7 by default)
  -w, --weekly strings    weekly snapshot at specified weekday@hh:mm,k (keeps 5 by default)
  -m, --monthly strings   monthly snapshot at specified day@hh:mm,k (keeps 12 by default)
  -h, --help              help for create

Global Flags:
      --ca string        path to root certificate for ssl usage
      --cert string      path to client certificate for ssl usage
      --color            output with color coding
      --config string    config file (default is $HOME/.pxctl.yaml)
      --context string   context name that overrides the current auth context
  -j, --json             output in json
      --key string       path to client key for ssl usage
      --raw              raw CLI output for instrumentation
      --ssl              ssl enabled for portworx

The example below creates a policy named p1 with the following properties:

  • Portworx performs periodic backups every 60 minutes and keeps the last periodic 5 backups
  • Portworx performs weekly backups every Sunday at 12:00 and keeps the last 4 weekly backups

Run the following command to create the p1 backup policy:

pxctl sched-policy create --periodic 60,5 --weekly sunday@12:00,4 p1

You can add schedule policies either when a volume gets created or afterward.

Here is an example of how you can add a schedule policy when the volume is created:

pxctl volume create --policy p1 vol1

The following example adds or updates a schedule policy later:

pxctl volume snap-interval-update --policy p1 vol1

The example below removes a policy from a volume by setting the snap interval to 0:

pxctl volume snap-interval-update --periodic 0 vol1

List schedule policies

Run the following command to list your schedule policies:

pxctl sched-policy list
Policy	Description
p1		periodic 1h0m0s,keep last 5, weekly Sunday@12:00,keep last 4

Update schedule policies

To update a schedule policy, use the pxctl sched-policy update command. Run it with the --help flag and you will see the list of the available options:

pxctl sched-policy update --help
Update a schedule policy

Usage:
  pxctl sched-policy update [flags]

Aliases:
  update, u

Examples:
pxctl sched-policy update [flags] policy-name

Flags:
  -p, --periodic string   periodic snapshot interval in mins,k (keeps 5 by default), 0 disables all schedule snapshots
  -d, --daily strings     daily snapshot at specified hh:mm,k (keeps 7 by default)
  -w, --weekly strings    weekly snapshot at specified weekday@hh:mm,k (keeps 5 by default)
  -m, --monthly strings   monthly snapshot at specified day@hh:mm,k (keeps 12 by default)
  -h, --help              help for update

Global Flags:
      --ca string        path to root certificate for ssl usage
      --cert string      path to client certificate for ssl usage
      --color            output with color coding
      --config string    config file (default is $HOME/.pxctl.yaml)
      --context string   context name that overrides the current auth context
  -j, --json             output in json
      --key string       path to client key for ssl usage
      --raw              raw CLI output for instrumentation
      --ssl              ssl enabled for portworx

Continuing our previous example with the p1 schedule policy, let’s make it so that our policy creates periodic backups every 120 minutes instead of 60:

pxctl sched-policy update --periodic 120,5 --weekly sunday@12:00,4 p1

Now, let’s make sure our new settings are applied:

pxctl sched-policy list
Policy	Description
p1		periodic 2h0m0s,keep last 5, weekly Sunday@12:00,keep last 4

Delete a schedule policy

To delete a schedule policy, run the pxctl sched-policy delete command with the name of the policy you want to delete as a parameter:

pxctl sched-policy delete p1
