The article will provide five highly practical tips to help you perform effective SQL Server Backups.
SQL Server is undoubtedly one of the best and secure data storage and backup software, but it also requires proper maintenance and management. Without proper maintenance, data is more susceptible to damage and may become unreadable. To understand the SQL Server Backup better, let’s have a look at some effective tips.
Storage Location and Backup Schedule
It is highly recommended to store backups at a separate location and this may save the users’ data in case of drive failure or damage. Even if the physical drive becomes faulty, users can use data from the stored location and can restore their databases easily.
With the passage of time, backups get prone to data loss if they aren’t scheduled regularly. Thus it is advised to create backup schedules which help the users in providing a consistent and regular history of their data.
Regular Full Backup and restoration
Full backups are useful tools which protect your data and ensure that no data is lost. Users should see the requirement of the organization to select a recovery method. Usually for smaller databases, full backup is recommended. It makes recovery easier and there are no unnecessary database logs. However, it might consume some good amount of disk space.
DBAs should regularly attempt restoration of backups on a test server to ensure safe recovery of all the data with all options that are required in restoration from the main server. This will keep their recovery plans in shape in the event of SQL Server corruption.
Use all Verification Options during Backup
Users should make use of all the options of verification which are provided during the database backup to get better results and a transactional consistent backup.
Users who use T-SQL scripts can add CHECKSUM parameter in the BACKUP command for better results. These steps only add levels of verification to the backup.
Differential Backups and Transaction log backups
Full backups are however necessary but are also expensive, so they can be replaced with differential backups of the databases. They are quite useful as they require less disk space and shorter processing time compared to full backups, but they should be performed more frequently.
Although differential backups are better alternatives, they will recover the data only up to the time of restore in the event of a crash arising out of SQL Server corruption. That’s why it’s advised to perform Transaction log backups as these backups contain the recent activities in the database and thus they could be used to restore the database to specific time. These backups can be performed even if the system is active.
Backing up System Databases
Users must have a backup plan for SQL server system database because it contains the system configuration and also SQL Server job information which must be restored if user is performing total system restore. The plan should be frequent and regular for backing up the system database.
The software SQLBackupAndFTP allows its users to backup along with user database and system database in just one click. Users can even schedule them and pick locations for backup.
