The backup policy means keeping the already saved data safer so that it isn’t accidentally deleted during the times of database dysfunction or emergency. The backup policy is a very tight and strict plan which provides full security to your files and basically everything that is on a particular machine or group of machines.
There might be two sets of tapes for every backup, once which is kept for local backup and the other, which is sent somewhere safe so that if the local backup is lost, the other tape saves the day.
Not just one, but there are a lot of other types of backup:
Incremental Backup
Once you’ve done the full backup one day, the next day you work but that doesn’t get backed up. Here’s where you use an incremental backup. Incremental backup is backing up on the part of data that didn’t have a full backup. If your full back up took place on Sunday, then the Monday’s work would be added as an incremental backup to the Sunday backup and so on!
Differential Backup
This type of backup would back up all the data all over again. If you’ve done a full cloud backup on Sunday, but had to undergo some changes with the data that you’ve backed up, this is where you need differential backup. This will backup every change, even if the data of that particular day already has a backup.
Why is a Backup Policy Necessary?
The most reliable way of saving your important documents is to have a backup. There’s no alternative to a backup and every IT company must have a full proof backup plan. The best way to backup is to create local backups first and then add them to tapes later for future reference. There’s nothing like a good backup policy for any company.
Regular and well-scheduled backups are very important but you cannot trust the machine with all the important documents. So, it is necessary for someone to manually keep an eye as well. If a very important data or file is lost, the IT section is often bearing the charge. Backup administrators are a major part of protecting the business, so a strong backup plan along with a good backup administrator is what every company needs.
Therefore, backing up is simple but must be very well executed. A company that has a good backup plan has everything under control.
