So i've been a bit stupid. trying to fix a backup issue that I honestly didn't know enough about. They have incremental backups setup. their drive was full so I went in and deleted the largest one to free up space. Now of course the largest one being the first and original backup.
I then went to acronis and clicked update and it created a new backup that was about 250GB, the other incremental backups were about 50-60gb each and the original was about 450gb. Has deleting the first backup invalidated all of the other backups? Is it going to be best for me to just clear it and start the whole backup process again?
I obviously shouldn't have deleted it without fully understanding, but it's done now and i'd obviously rather know if it is a bleep up and if I need to re do everything. I feel stupid, but hey ho, I've learned my lesson.
