Wanted to see what others had seen with this.
Basically we have all vm backups set to incremental forever, and no minimum retention per our installers recommendation. The idea being it would keep as many as possible and roll them up when needed.
Last week 80% of our machines rolled up to the last days backup. This removed every single backup we had for most of our machines. I spoke with support and was told this was how it would function if no retention period was set on the machines. I can't think of a situation where it would ever be acceptable to not have a retention set if you were risking cutting backups down to 1 day.
Basically wanted to see if anyone else had noticed this behavior. I've emailed our installer and waiting to hear back from him on how we ended up in this situation. It isn't currently a problem and retentions have been set, but wanted to hear if others had seen something similar.
