How Often Should You Backup SQL Database?

Usually the backup process is the mixture of complete backup, incremental backup (differential), and transaction log backup. There are different types of backup frequency policies that organizations can adapt according to their need.

  1. Weekly: According to this backup policy, complete database backup is taken every week or 168 hours. Besides, the differential backup is done every day. This type of backup is usually chosen for databases that have only a few transactions every week or contain less important data. A good example can be the payroll database of a tiny business company where very little changes are done usually and any lost data can be recreated easily.
  2. Daily Once: This is a simple backup policy where the complete backup is done every 24 hours without any differential backup. This policy is ideal for small companies with more transactions than the company mentioned in the earlier point. Usually, companies that issue manual receipts need this type of backup. As there are manual records, any lost data can be recreated with its help.

  4. Daily Six Times: This backup policy can be termed as the through backup. As per this policy, complete backup is done once every 24 hours, differential backup at every 4 hours and transaction log backup every 1 hour. This policy is for the organizations that will face disastrous consequences or interruption in business functionality if any data loss occurs. Mid-sized retailers and large enterprises usually adopt this policy.
  5. Daily Eight Times: This policy has been designed for the database that is busy and contains business-critical data.

Large online retailers, commercial bank, and hospitals are the main subscribers of this policy.
