SentinelOne taking storage space

SentinelOne is a new Anti-virus that V2cloud is using.

One of the features that are enabled is VSS (Volume Shadow Copy Service), this takes up about 10% of storage space of your cloud computer, but it does enable the option to rollback singular files that are corrupted/infected, SentinelOne will automatically detect if a file was infected and rollback to a uninfected version. This is an option that can be turned off, but you will lose the function to rollback specified files. This will lead to more downtime as to restore files will take longer.
