How do you make your backups faster and use less space?

1 Choose the right backup type

There are different types of backups, such as full, incremental, and differential. Full backups copy all the data from the source to the destination, but they take the longest time and the most space. Incremental backups copy only the data that has changed since the last backup, but they require a full backup to restore. Differential backups copy the data that has changed since the last full backup, but they take more space than incremental backups. Depending on your backup frequency, retention policy, and recovery objectives, you should choose the backup type that best suits your needs.

2 Compress and deduplicate your data

One way to reduce the size of your backups is to compress and deduplicate your data. Compression reduces the amount of bits needed to store the data, while deduplication eliminates the duplicate blocks of data. Both techniques can save you space and bandwidth, but they also add some overhead to the backup process. You should test different compression and deduplication levels and algorithms to find the optimal balance between speed and space.

3 Use incremental-forever backups

Another way to make your backups faster and use less space is to use incremental-forever backups. This is a backup strategy that combines full and incremental backups, but eliminates the need for periodic full backups. Instead, you take one full backup at the beginning, and then only incremental backups afterwards. The incremental backups are then synthesized into synthetic full backups on the destination, which can be used for restore. This way, you can avoid the performance impact and storage consumption of full backups, while still having the benefits of fast and easy recovery.

5 Use backup software and hardware

Finally, you can make your backups faster and use less space by using backup software and hardware that are designed for this purpose. Backup software can help you automate, manage, and monitor your backup process, as well as provide features such as encryption, verification, and reporting. Backup hardware can help you improve your backup performance, reliability, and scalability, as well as provide features such as caching, deduplication, and replication. You should choose backup software and hardware that are compatible with your system and your backup goals.
