Windows 7 backup disk space management consists of three parts: system protection, automatic backup and image. In order to save backup or protect space, put them in an article summary, introduce the deletion or adjustment method of backup space, how to better Maximize disk space savings.

However, Windows 7 does not allow protection of non-system drives only, but does not protect the system drive, so as long as system protection is turned on, you must first turn on the protection system disk.
2, adjust the disk space usage
The system disk defaults to 3% of the maximum space, the general default can be, no matter how much, the system disk must reserve at least 1G of disk space, otherwise the restore operation will not be able to get on.
The system disk does not take up to 30% of the maximum space by default. It can be adjusted according to the actual partition size. If the drive contains important files, or if it is left for Windows 7, it may be used at a critical time.
2, delete the early restore point release space
Please note: you can not delete the individual restore points, either delete all restore points (can be deleted in the system protection window), or delete the most recent restore points All restore points (only in Disk Cleanup - "More Options -> System Restore and Shadow Copy in the click clean). The effect of deleting a restore point is only to temporarily release the disk space, which will occupy this part of the disk space. So ultimately it depends on the system to protect disk space settings.
