Snapshot creating several useless partial snapshots out of the schedule

Snapshot creating several useless partial snapshots out of the schedule, consuming a lot of server disk memory.

I have left only one scheduled snapshot at my site KaZas.com.br that should run weekly and save the backup at Google Drive, but last night Snapshot PRO tried to create a snapshot backup (out of the schedule since my last one was created on Feb 26th and therefore the next one should be created only Mar 5th).

Due to the issues related at this post: https://premium.wpmudev.org/forums/topic/my-website-goes-down-when-im-trying-to-create-a-snapshot (please check my last reply on Feb 26 2018, 7:28:16 PM), it not only took my site down several times during the process but despite of Google Drive be configured as its destination it created a folder at wp-content/uploads/snapshots/_backup with several partial backups that are useless and consumed about 1.4GB (https://ibb.co/j7oaA7).

It seems like Snapshot plugin needs to go under a major review.

Sincerely,
