Backup and verification operations can create significant increases in network traffic. This can lead to reduced performance of your servers and all of the segments of the network involved in the backup. One solution to the problem of course is scheduling backups at a time when network usage is low, like before or after hours. Since this may not always be possible, you can perform backups in smaller incremental steps during normal hours.
Business Data Backup Options
These offers the ultimate in data protection by backing up the entirety of a system’s files and folders. Everything is stored as part of a set, so keeping track of backups is a pretty straightforward affair. On the downside, this approach often takes a toll on storage and bandwidth, not to mention the time it takes to run a full backup.
These contain the files that have been added or changed since the last full or incremental backup. This allows for shorter backup windows and typically requires less storage space since it builds upon an existing backup. One disadvantage of using this method is that it takes longer to restore data from an incremental backup since it requires a full backup and subsequent incremental backups to retrieve the desired data.
Differential and incremental backups may sound similar, but they serve different purposes. Differential backups will contain files that have changed since the last full backup, an approach that saves storage space since only a full backup and the last differential backup is required for restoring data, versus a full backup and multiple incremental backups.
Finally, synthetic full backups are typically used in situations with tight backup windows. It takes data from a full backup and incremental backups to create another full backup, blending the benefits of each backup type, namely completeness and lower resource impact, respectively.
