SharePoint Backup and Recovery Best Practices
Following best practices is must, if you want the best performance at lowest resource usage. Backup and restore process can consume server resources and also limit the performance of the server. But, if you follow the below mentioned best practices then it will increase the performance of the servers, resource utilization will decrease and the backup and restore process will increase.
Minimize the latency between SQL Server and Backup Location – The best for backup is to use the local drive on the database server instead of using the network drive. Later, the data copied can be transferred to a shared folder on the network. But if you use the network drive, the database will perform faster with 1 millisecond or less latency, but the most backup process will consume all I/O available resources. So, in order to avoid complete I/O resource utilization perform the main backup process to the different drive from the drive running SQL Server.
Smaller the content database faster the recovery – If your databases file size is smaller the recovery can be done very faster. Therefore, it is recommended, if possible, try to make multiple content database backup for Web application instead of creating one big content database.
Prevent processing conflicts – Try to make staggered backups so that not all databases are backed up at the same time. Also, avoid backup process when any users need access to the system.
Always go for incremental backups for bigger database – If you are making a backup of any larger database then you must go for incremental backup as it can be restore quickly and more successfully than full backups.
