What Is System Backup?

System Backup is a type of backup aiming at imaging system partitions and other system-related partitions (such as system reserved partition and boot partition), including system files, boot files and data on these partitions.

System Backup is different from partition backup and disk backup. Partition Backup is used to back up partitions you select, you can select D:drive, E:drive, F:drive to be backed up, etc; Disk Backup is to back up all partitions on the specific disk, including all data on that disk.

For instance, there are 3 partitions on the disk: C: (system), D: (Data) and E: (Data). If you run a "system backup", only C:drive will be backed up as usual. If you run a disk backup, all partitions, including C: D: and E: will be backed up.

If you would like to back up and recover the whole system disk containing system, installed software, games, applications as well as personal files, the disk backup is suggested.

It is also recommended to regularly run a system backup in case of a system crash. Then you can restore your system with the system backup image.

1. If you would like to restore a system backup image, please use the feature "System Restore".

2. If you would like to view the contents of system backup without restoring a backup image or you would like to copy some files and folders in the backup image, you can use the feature "Explore Image" to mount the image.

  • As System Backup is a one-click solution, so your system partition and system reserved partition will be selected as backup resource automatically in Step 1. If these partitions are not listed automatically, check whether this system drive is 4096 bytes per sector disk. AOMEI Backupper doesn't support drives with 4096 bytes per sector at present.

  • If your system drive is a dynamic disk, then System Backup in the standard version is not supported.

  • System backup files created by dynamic disks are not supported to recover to dynamic disks. It can be recovered to the original location or a basic disk.

  • You can back up C: drive via Partition Backup but we suggest you back up it via System Backup. If you back up C: drive via Partition Backup, the system may not boot after doing the restore.

  • Generally, System Backup backs up “system” partition, “boot” partition (C: drive) and recovery partition but it won't back up OEM recovery partition.

  • For encrypted system partitions, Backupper uses the sector by sector method to backup the system by default.

  • Backupper supports backing up windows systems only.

  • To customize the advanced configuration for the current backup task, please see Backup Options, Schedule Backup and Backup Scheme.
