We currently have a WSS 3.0 setup on one of our servers. I use a backup script every night to back up Sharepoint using "stsadm.exe -o backup ...". For some reason last night's backup is taking forever (much longer than normal). Is it safe to just close this command prompt window to return Sharepoint to a read/write state? I don't want to break anything, but business has started and we need to be able to make changes to Sharepoint.
