Same reason, read is on one drive and write is on another drive. Better if you can directly RAR to the destination server using network share. It has two benefits:. By the time you are done with the backup, RAR, copy over network, restore on the other server, the Transaction Log file LDF on the primary database server might become very big.
For us, it becomes around 2 to 3 GB. So, we have to manually take a transaction log backup and ship to the secondary server before we configure Transaction Log Shipping. When you are done with copying the transaction log backup to the second server, first restore the Full Backup on the secondary server:. This generally takes a long time. Too long in fact. As a result, it takes a long time to do a transaction log backup, copy and restore and it takes more than an hour to restore it.
So, within this time, the log file on the primary server again becomes large. As a result, when log shipping starts, the first log ship is huge. So, you need to plan this carefully and do it only when you have least amount of traffic.
I usually have to do this manual Transaction Log backup twice. First one is around 3 GB. Second one is around MB. Now you have a database on the secondary server ready to be configured for Log shipping.
Shrink the Log File. Go to Primary server, bring on Database options, go to Transaction Log option and enable log shipping. Remember, the first path is the network path that we tested from command prompt on the secondary server. The second path is the local hard drive folder on the primary server which is shared and accessible from the network path. So, the path you specify is on the secondary server. I just have same folder configuration on all servers. It can be D:tranlogs if you have the tranlogs folder on D: drive on secondary server.
So, force disconnect of all users when database backup is being restored. Setup a Monitor Server which will automatically take care of making secondary server the primary server when your primary server will crash. Even if you did all the paths, and settings wrong, you will still see it as successful. If the job is not there, your configuration was wrong.
Wait for 15 mins to have one log ship done. Then refresh and see the list. If you see all OK, then it is really ok. If not, then there are two possibilities:. See if the Log Ship Copy job failed or not. If it fails, then you entered incorrect path.
There can be one of the following problem:. You probably took some manual transaction log backup on the primary server in the meantime. As a result, the backup that log shipping took was not the right sequence. The granting of new service account for SQL Agent should be from SQL configuration manager, then we don't have to add the service account to the group. Configuratoin manager will do it for us. This is the recommended method from Microsoft as the change of SQL server service account also reult do the encryption key as well.
The log shipping of SQL Server is just a bit differnet from The service account assignment and the UI. Thanks for an excellent expalnation I did test it and its working when you have two seperate servers.
I'm using sql on one server but I do have the secondary database on the same server but on a partitioned drive now the problem is that the secondary database is growing how do I shrink it.
Database engine is on c drive whereas the secondary database and all the data that I'm collecting is sitting on d drive on the same server. From my point of view, log shipping doens't work like mirror, they work in slightly different way.
Thank you Omar. This was an excellent document. I was stuck with the user rights issue for a couple of hours. Reading this document helped me fix the problem immediately. How to make a full backup on primary server, if database on primary server is in log shipping proces. Need details how SQL server startup account communicates across both primary and secondary server via network. SQL server startup accounts are sql in both servers with same password , log ship works fine , but can u explain me how id communicates during copy process since id communication will be from Asql to Bsql how does it get matched.
Thanks omar. I would appreciate all your efforts. Request you to publish the article on. The scheduler can be defined to run with a polling period in a unit of minutes, hour or day. By default, the setting is to run a backup job in a time gap of 15 minutes. The job execution polling period depends on the backup plan because it is dependent on the reading of a number of transactions in n minutes in the database, Transaction Log backup size and very important thing RPO Recovery Point Objective and RTO Recovery Time Objective.
Once database backup is scheduled, the SQL Server transaction log backup process will be started to create one full backup of the database. Now, at the secondary or disaster recovery site, that transaction log backup needs to be restored to make it in use as primary when disaster happens. Click on the Add button, SQL Server will ask to add the instance name and database details on which transaction log backup is going to be restored.
On a successful connection, the database name will be visible in the drop-down list of the Secondary database field. The user needs to select the database name, on which a user wants to restore the SQL Server Transaction log backup.
Before shipping the transaction log at the secondary site, a full backup of the primary database must be required to restore at a disaster site or secondary instance end.
To perform the restoration of a full backup, SSMS will ask to perform restore operation with three options. This option will take a full backup of the primary database on the backup folder directory by the backup job and then the backup will be copied to the secondary server and then the backup will be restored on the secondary database.
If already database full backup is generated by the user or exists, then the user will be asked to specify the network path of that full backup. Once a backup is verified, a copy job will move that backup file to the secondary site and backup will be restored by the scheduler job. No, the secondary database is initialized. When a backup is manually restored by the user at the secondary site, then this option will be selected.
When a user wants to configure SQL Server Log shipping for the large-sized database, then database administrators always use this option. But make sure that the database needs to be restored with No recovery or Standby mode. Copy files screen will ask the user to fill up the destination folder for copied files on the secondary or disaster site.
Usually, that folder directory path should be located on the secondary server. Transaction log backup will be restored on the secondary database from this directory. You will find one more parameter, Delete copied files after. Create a free Team What is Teams?
