14 Free Folder and File Synchronization For External Hard Drive Backup

Updated: October 10, 2016 / Home » Desktop Computer Software » Data Recovery and Backup Software

The number 1 mistake by most people is to save everything onto their external hard drive and calls it a backup. This is not the correct way, just because you save everything to your external hard drive doesn’t make that a backup copy. A backup copy is when you have duplicate copies of the same files, one copy in your desktop or laptop, the other in your external hard disk. Why is it important to have 2 copies? By having 1 copy on your external hard drive, what happens when you lose that backup hard drive? What if the external hard drive crashed? That is why you always keep 2 copies as an insurance.

↓ 01 – Paragon Backup & Recovery | Windows

The most powerful free backup solution ever! Take complete control of your PC’s safety. Create a backup of your data today. Based on solid commercial backup and recovery software from Paragon, the new Backup & Recovery 14 Free Edition will give you a rich set of features that you can trust. Backup Features:

  • Disk backup to save not only all on-disk information but also the system service structures. It is ideal for making a backup image of an entire hard disk (including GPT-discs) or system partitions to guarantee the operating system’s working capability
  • Differential backup to a sector image to only archive changes since the last full sector-based image, thus considerably saving the backup storage space. To restore this kind of backup you will require a full image and one of its differentials
  • Backup Capsule – You can place a backup image to a special secured place on the hard disk called the Backup Capsule that has an independent system layout (e.g. a separate partition) and will stay operable should the active file system be damaged. To avoid an accidental removing or unauthorized access of the backup data, this partition is hidden and thus cannot be mounted in the operating system
  • Back up separate partitions or entire hard disks to a pVHD (Paragon Virtual Hard Drive) format – a special VHD, optimized for storing backups of virtual and physical machines
  • Back up changes since the full, or the latest incremental image. It’s allowed to maintain several incremental chains based on one full image, provided each chain contains changed data of a particular backup object(s). pVHD based incremental imaging works much faster and rock-stable in comparison with the old PBF
  • Universal Image Mounter (UIM) – Mount pVHD backup images to browse their contents and retrieve data both, in the program and directly under Windows OS

↓ 03 – DirSync Pro | Windows | Mac | Linux | DOS

DirSync Pro is a small, but powerful utility for file and folder synchronization. DirSync Pro can be used to synchronize the content of one or many folders recursively. Use DirSync Pro to easily synchronize files from your desktop PC to your USB-stick (/Externa HD/PDA/Notebook, …). Use this USB-stick (/Externa HD/PDA/Notebook, …) to synchronize files to another desktop PC.

Using DirSync Pro you can make incremental backups. In this way you’ll spare lots of time because you don’t have to copy all the files each time you want to update your backup; only new/modified/larger files would be copied. DirSync Pro provides some preconfigured modes (e.g. Mirror, Backup, Contribute, ?) for common synchronization and backup tasks and some custom modes in which the user could set up the synchronization behavior to meet specific wishes. Prior to synchronization, DirSync Pro perfoms an analysis on files and folders and detect any kind of changes to any file/directory in the source. If a file is for example modified, removed, deleted, renamed in the source DirSync Pro synchronizes the destination accordingly. DirSync Pro detects also changes to file meta data (e.g. DOS attributes, POSIX file ownerships/group/permissions) and could preserve them to the destination file/directories.
