I have an SCR server that has run out of disk space; how long can an SCR be suspended? is there an impact on the source side? should I have suspended the scr or just let it run? exchange 2007 thanks

Hi, Suspending SCR will affect your repliaction between source and target and you will have replay copy length in source server, Also if you have configured replay lag time and log truncation lag time high then you should not suspend it for long time else your logs would not purge at source side. If you need to do any maintenance for long time then you can disable SCR and can re enable it. Please find this below article for clear understanding.

Agree with Anil. You can disable the SCR at first, switch a big disk on the target machine, and then enable the SCR againJames Luo TechNet Subscriber Support (http://technet.microsoft.com/en-us/subscriptions/ms788697.aspx) If you have any feedback on our support, please contact tngfb@microsoft.com
