Disable replication globally

Use this procedure to disable backup transfers for all PNs. If you want to disable backup transfers for a given PN, simply disable replication for that PN only.

Quorum does not recommend that you disable backup transfers globally, unless your configuration is an HA‑only configuration, meaning you don’t have a DR Appliance; if you have an HA‑only configuration, disabling all snapshot transfers saves space and improves performance on your HA Appliance.

However, there are situations in which you might need to temporarily disable snapshot transfers globally. Before you do so, you must have enough disk space to accumulate backups.

If the HA Appliance cannot communicate with the DR Appliance, it will retain the backups in its queue and transfer them when the DR Appliance comes online.

An alternative to disabling all transfers is stopping protection on the HA Appliance so as to keep the repositories in sync, but the downside is that the HA Appliance will not perform any backups until you turn on protection. This method is not recommended. Besides, when you re‑enable transfers, the repositories will resync automatically.

To disable replication globally:

1.	Log on to the onQ Appliance’s onQ Portal.

2.	Ensure that your onQ Appliance has enough disk space to accumulate backups. For the related alert, go to Recovery Node and PN Disk Space Alerts.

3.	Go to APPLIANCE CONFIG tab > onQ (REMOTE) page > MODIFY button.

4.	Do one of the following:

•	(Recommended) Set the bandwidth to zero.

•	Change the DR Appliance’s/DR Mirror’s IP address to an unused IP address or disconnect the DR Appliance/DR Mirror from the network.

5.	Stop protection.

6.	In the Enable DR Transfer? field, select the No radio button, then Proceed.

Disable Transfer: ON icon no longer displays at the top of each UI page on the onQ Appliance.

7.	Start protection.
