Losing valuable information can cost you time and large amounts of money. Before this happens, backup your information and data to protect yourself or your business from a huge loss. There are a few steps to think about when learning how to backup, recover, and restore your data.
Things to Consider
The first thing to come up with is a restore strategy for backing up information and data. When backing up data, thinking about how often you will need to do the backup, what type of hardware is required, where the files will be stored, and how the backup will be tested. The second part comes with restoring the data.
When coming up with a strategy and testing it, write it down as you go so you can use the same procedure in the future. There are different recovery models to think about with your data. Depending on your requirements, you can use either a simple or full recovery model.
Building a Strategy
Once you have a recovery model to meet your specific needs, it is time to build a backup strategy that corresponds to that model. To design the best backup strategy, you will need to think about a few factors. How often during the day to applications access the database? If you have an off time, the full database backup should be performed then to prevent any delays while working.
How often are updates and changes going to occur? If changes are going to be frequent, schedule differential backups between the full database backups while in simple recovery mode. The differential backup will get only the information that has change since the last full backup. For the full recovery mode, schedule frequent log backups. By having differential backups between the full backup, you can reduce the amount of time and number of logs you need to restore after losing the data. This will make it so you can get your information back faster and get back on track.
Are changes going to occur in a large or small part of the database? If the changes happen in a large part, then partial backups will be useful. In addition, you can backup certain files or part of files to make it go even faster.
Space for a Full Backup
Before you start backing up information, estimate how much disk space you will need for a full backup. The backup will contain copies of all of the data in the database and the amount needed is normally smaller than the database itself. Making sure you have enough space is extremely important because you do not want to be in the middle of a backup only to find out you need more space.
Backing up your information should be started as soon as your business is running. The backup data will be easier to recover and restore if you are proactive about the situation. Think about when and where the backups will need occur as well as how often they should be performed. This will save you a lot of time, money, and hassle in the case of a data loss.
