What Is Deduplication for Companies?
Among the top expected features of backup software, there have always been reliability and ease of use. Data deduplication directly supports two of these.
Actually, you can integrate the most of deduplication software into existing storage infrastructures, so no one should worry about the tricky interface. The reliability is provided by constant verification, looking after the faults, and healing.
Choosing the Best Deduplication Option
The two main types of data deduplication are the source and the target ones.
- Target deduplication reduces the amount of disk needed to store your data, but it does not change the amount of bandwidth needed to get the backups to the server. So this approach can be recommended to the companies which don’t boast the great bandwidth.
- Source data deduplication requires you to use different network server backup software. That way, if a file has already been backed up by the backup server before it won’t be again transferred across the net. This reduces the amount of disk space required to store your data as well as the amount of bandwidth necessary to send the data.
What Should You Check, When Purchasing Storage Deduplication Software?
If you want to perform a quality network backup in your company and are not sure what to choose, we strongly advise you to look after the following data deduplication features:
- Speed (obviously)
- Replication (in case of network distributed backups)
- Smooth restore (centralized management should be present)
- Feedback (there is no better way to find out about any software product)
