We have a remote disaster recovery site for our databases which is kept up to date through log shipping. Our former DBA set this up and it worked great, but he has since left and when the passwords for the logins were changed after his departure they forgot to update the passwords for the SQL services on the disaster recovery site. This happened in July and I only found out about this today. We have updated the passwords and restarted the services, but it's been more than 5 months since the last successful log restore. The log backup and restore frequency was set to 15 minutes, with a threshhold of 1440 minutes. Because the latest successful restore has well and truly surpassed this threshhold, the logs are no longer being restored.
We currently do not have a DBA, and we lack the necessary knowledge on how to correct this. Can anyone please tell me how we can get the log shipping started again? Do we have to do a full backup/restore first? We're rather concerned that if we would get things going again the transfer of 5 months accumulated data will incapacitate our network.
Any help will be appreciated.
