I know running VM on a snapshot is not good in terms of performance and disk space. I have seen a client who runs a VM with a snapshot for a long time (two months so far). The reason they keep the snapshot because the application breaks when the backup runs every day so they decided to keep the snapshot. I can not find any documental evidence to giving them that if you run a VM with snapshot more 74 hours then chances the will break. As far as my client concern It is running ok and they want to keep it as it is. Will they get a nasty surprise one day keeping the snapshot?
What would happen if you run the VM with a snapshot?
