Sql Server Log Shipping Monitor – Log Server SQL shipping provides a DR (disaster recovery) solution for SQL Server databases, configurable at the database level. Once selected, a backup copy of the SQL Server transaction log is taken, copied to the target page and returned. This entire process or solution is performed by a SQL Server function, each step of which is configured by the user. A student may have trouble in many areas, while troubleshooting, but for an experienced user it is very easy to set up and handle SQL Server login shipping setup errors.
Transaction logs contain a log of all transactions that occur in a SQL Server database. This is very useful to prevent data loss in the event of a system crash, if you are new to SQL Server transaction logs, these logs are explained here, A Beginner’s Guide to Logs SQL Server communication.
Sql Server Log Shipping Monitor
The SQL Server instance from which the transaction log backup is sent is called the first, and the SQL Server instance from which the transaction log is backed up is called the second in the ship. login SQL Server. Before starting the SQL Server log shipping setup, the database must be in a full recovery instance or the bulk logging must be included in the SQL Server log ships. If your database is not in a fully restored or mostly written model, the T-SQL statement below can help set it to a fully written model.

Here, publisher is the name of the database at the end of the primary server. Even the data recovery template can be changed through SSMS again using the dialog below:
If your database is not included in the recovery model in most or most cases, the SQL Server Log will return an error as “This database cannot be the primary database in the configuration ship for the log and use a simple recovery template. You must use a recovery template that is fully written before creating transaction logs.”
As a first step, the publisher database must be enabled to configure SQL Server logging ships. To enable SQL Server logging on the primary endpoint, open the database property or expand the database taskbar in SSMS.
Troubleshooting Log Shipping Issues In Sql Server
Click on Shipping Logs; a checkbox will be available named Enable this as the primary database in the ship configuration. Select this checkbox to continue:
As mentioned above, the database must be enabled for this SQL Server log shipping configuration. When this check box is selected, the user is allowed to schedule a SQL Server transaction log backup job.
The Backup Settings button allows the user to set a backup schedule for the SQL Server transaction log.
High Availability Vs Disaster Recovery
The SQL Server Backup Settings screen allows you to edit the path to the backup folder. Both the network path and the file system path must be specified in the form. This is the location of the file system where the backup operation leaves the transaction log and lifts it for copying and restoring to the secondary server. You will see more fields in the dialog box.
Alert if backup does not occur within the parameter alert if backup does not occur within (n) hours/minutes/days.
For example, 72 hours is defined for Delete files older than the parameter value. This will delete the file from the file system after 72 hours. Check if the file needs to be copied to a destination or secondary server before deleting. If no duplicates appear from the primary database within 1 hour, an alert will appear because the value of the setting is Warn if there are no duplicates for 1 hour on the top screen.

Users also have the right to change the name of the add-on if they want to change it.
Click the Add button on the Transaction Log Backup Setup form. It allows the user to configure the work items. It can be set to work with the polling time in minutes, hours or days. By default, the setting is to run the backup every 15 minutes. The polling time of the task depends on the security plan because it depends on reading the number of transactions in (n) minutes in the database, the size of the backup copy of transaction log and critical RPO (Recovery Point Objective) and RTO (Recovery Time Objective).
When a database is created, the SQL Server transaction log backup process is started to create a complete database backup. Now, on the secondary site or disaster recovery site, that backup transaction log must be restored for primary use in the event of a disaster.

Click the Add button, and SQL Server will ask you to add the instance name and details of the database from which the transaction log will be restored.
The secondary server instance field can be populated with the name of the SQL Server instance or the SQL Server instance’s IP address and port number. After a successful connection, the name of the database can be found in the drop-down list of the Secondary database field. The user must choose the name of the database he wants to restore from the SQL Server marketing software.
Before sending the transaction log to the secondary site, a full backup of the primary database is required for disaster recovery or the termination of the secondary instance. To perform a full backup restore, SSMS will prompt you to perform a restore operation with three options.

Yes, create a full backup of the primary database and restore it to the secondary database (and create the secondary database if it doesn’t exist). This option creates a full backup of the primary database in the backup folder directory via backup, then copies the backup to the secondary server, and then restores the backup to the secondary database.
Yes, restore a backup of the primary database to the secondary database (create a secondary database if it does not exist). If the user has already created a full backup of the database, or one exists, the user will be prompted for the network path of that full backup. After the backup is confirmed, the copy function moves that backup file to the second location, and the scheduler function restores the backup.
No, the secondary database is initialized. When the user returns the attachment to the second location, this option is selected. If the user wants to configure SQL Server log delivery for a large database, database administrators will always use this option. But check if the database needs to be restored without recovery or hibernation.
Dashboards For Sql Server Monitoring
The file copy screen prompts the user to fill in the destination folder for files copied to a secondary or malicious site. Ideally, that folder directory path should be on the secondary server. The transaction log backup is restored to the secondary database from this directory. You will find another parameter, Delete duplicate files later. As in the first point, the transaction log backup is deleted from the file system after (n) hours/days.
Here, 72 hours is defined for the above SQL Server log sending configuration. Then the SQL Server transaction log backup is deleted after 72 hours. The user is also allowed to change the name of the copy function.
Users can configure the copy job scheduling property defined in the screen below. Each parameter comes with the definition of a function call time. Here we have used the default value of 15 minutes for this setting.
Restoring Microsoft Sql Server Items
The last step on the second page is to configure the SQL Server transaction log recovery process. The database must be in non-recovery mode or standby mode when the transaction log is sent to the secondary. Users are asked to select one of them (without recovery / hibernation).
Delay recovery and Warn if recovery occurs are two options in the transaction log recovery step. If the user wants to delay restoring the database after copying, the delay can be set to (n) in minutes/hours/days. If an attachment is returned within (n) minutes, an alert will be sent to the configured email list.
Users can configure the job scheduling property defined in the screen below. Each parameter comes with the definition of a function call time. Here we have used the default value of 15 minutes for this setting.
Step By Step Configuring Alwayson With Log Shipping
When saving the log shipping configuration, the configuration is saved and a job is created on the first end and the second end. The screen below will show you the status of each logging operation. If an operation failed, status failed with an error message, see the screen below.
After successfully setting up the ships for the database, the user can
