Used Shadow Copy Storage space: 0 B
Allocated Shadow Copy Storage space: 0 B
Maximum Shadow Copy Storage space: 3 GB
Used Shadow Copy Storage space: 102.406 MB
Allocated Shadow Copy Storage space: 400 MB
Maximum Shadow Copy Storage space: 3 GB
Used Shadow Copy Storage space: 211.297 MB
Allocated Shadow Copy Storage space: 500 MB
Maximum Shadow Copy Storage space: 3 GB
