  • Extended Backup Windows: The process may consume more time.
  • Elevated Storage Requirements: The strategy demands substantial storage capacity for instant file backup.
  1. Incremental Backup Strategy:

Focus: Capturing Altered or New Data Since the Last Backup

The incremental backup strategy centers on identifying and backing up only the data that has undergone modifications or is newly created since the previous backup. This approach effectively conserves storage space and accelerates backup execution, as it does not require the duplication of unchanged data.


  • Reduced Storage Footprint: Incremental backups economize storage resources.
  • Expedited Backups: The process is typically swifter than full backups.
  • Minimized Network Congestion: Less data needs to traverse the network.
  • Lengthy Restoration Processes: Retrieval may necessitate multiple incremental backups.
  • Dependency on Prior Full Backup: Incremental backups rely on a prior full backup for restoration.
  1. Differential Backup Strategy:

Focus: Capturing Data Changes Since the Last Full Backup

Differential backups focus on cataloging data alterations that have occurred since the last full backup. Unlike incremental backups, differential backups do not necessitate previous backup sets for restoration, simplifying the process.


  • Faster Restoration Compared to Incremental Backups: Restoration times are quicker, as only one differential is required.
  • Reduced Storage Demands Relative to Full Backups: The storage requirements are lower compared to maintaining multiple full backups.
  • Longer Backup Windows: The process may require more time compared to incrementals.
  • Increasing Restoration Times: The time taken for data retrieval increases with the number of differential backups.
  1. Synthetic Full Backup Strategy:

Focus: Simulating a Full Backup Utilizing Incremental or Differential Backups

Synthetic full backups amalgamate incremental or differential backups to create a comprehensive and autonomous backup set. This strategy harmoniously combines the advantages of full backups with the efficiency of incremental backups.

  • Reduced Backup Window: Synthetic full backups consume less time than full backups.
  • Lower Storage Requirements: They are less storage-intensive than maintaining multiple full backups.
  • Processing Overhead During Creation: Creating synthetic full backups requires computational resources.
  • Longer Restoration Times Than Incremental Backups: Data retrieval times may be longer compared to incremental backups.
  1. Mirroring Strategy:
