What is a backup?
A backup is a copy of data and information that is stored in a secure location to restore them in case of loss, damage, or any other data problem. Backups are essential for ensuring data security and availability and serve as the last line of defense in emergency scenarios.
Typical backup strategies:
❌ Full backups: A complete copy of all files and data that is created regularly. This is the most traditional approach but can be time- and storage-intensive.
❌ Differential backups: Only save the changes made since the last full backup, which shortens the recovery time but requires more storage space than incremental backups.
❌ Incremental backups: Only save the data that has changed since the last backup – whether full or differential. This method is storage-efficient and allows for quick daily backups.
Modern backup technologies:
✔ Cloud backups: Allow data to be stored in the cloud, providing flexibility and offsite security. They are ideal for scalable storage needs.
✔ Disk-to-Disk backups: Uses hard drives for quick and reliable data backup. This approach provides fast backup and recovery times.
✔ Tape backups: A proven but older approach that can securely back up large volumes of data at a low cost. They are durable but not as performant as other methods.
Measures for data backup protection:
✔ Regular backup checks: Ensure that backups are regularly tested and validated to guarantee that restoration is possible in case of an emergency.
✔ Offsite backups: Store backups at an external location to protect them from physical constraints like theft or natural disasters.
✔ Encryption of secured data: Protect sensitive data through encryption to ensure that no data is disclosed in case of unauthorized access.
