Manage stored data

Setup → Stored data shows what the workspace stores and is billed for. Editors can see it. To change retention or delete data, you need the Admin or Owner role. The page’s cards, units, and retention rules are described under Setup: Stored data.

See what the workspace stores

1. Open Setup → Stored data.
2. Read the totals for what the workspace pays for now.
3. In the readings table, find the parameters with the most records, and the retention that applies to each.

Set how long readings are kept

Deleted readings cannot be recovered.

1. Open Setup → Stored data.
2. Under Readings retention, select Change on the default.
3. Choose Keep everything or a number of days. The default applies to every parameter that no rule covers, and to readings of deleted parameters.
4. Check how many records the dialog says the change deletes, then save.
5. To keep some parameters for a different time, select Add rule. Choose the parameters or branches and the number of days, or keep them for ever, then save.

A rule for a branch also covers parameters added to it later. The most specific rule wins.

Delete readings

Deleted readings cannot be recovered.

1. Open Setup → Stored data.
2. Choose what to delete:
   • All parameters: select Delete readings… on the Readings card.
   • One parameter: select the trash button on its row.
   • Some parameters or branches: select them in Setup → Parameters and select Delete readings… in the toolbar.
3. Choose Older than a date, In a period, or All readings.
4. Check the number of records the dialog will delete, then confirm.

The deletion runs in the background. You get a notification when it finishes.

Shorten the activity history

1. Open Setup → Stored data.
2. Under Activity history, either:
   • Select Change and set a retention of at least 30 days, or keep everything.
   • Select Delete old history… and choose a date at least 30 days ago.

Checkpoint reverts keep working after the deletion.

Shorten the alarm log

1. Open Setup → Stored data.
2. Under Alarm log, either:
   • Select Change and set a retention of at least 30 days, or keep everything.
   • Select Delete old log… and choose a date at least 30 days ago.

Active alarms stay as they are. The alarm log itself is described under Alarm log.

Let the assistant do it

Ask the assistant to change retention or delete data. It shows what it will change and asks before it changes anything. Scripts can use the storage.* API procedures, listed in the procedure reference.
