Google Drive lost all our HR files, everyone's contracts etc. Huge panic. We only got them back by using Vault (the legal discovery back door, which doesn't return them in the same format or folder structure). And yes, no one deleted them - I checked the audit logs. If we weren't firefighting so bad here I would be pushing for us to switch.
I'm not judging, but I just don't understand why someone would save business critical data to Google Drive only. Is this a US thing? Aren't you afraid of privacy or trade secret leaks and potential legal ramifications?
One of the consequences of SAAS being easier to use to than old school local IT is that these decisions are often made by the user of the data directly, for whom these are often not the most salient risks. In the old days you couldn't really operate beyond a few people without a sysadmin who would know that they would be fired if something like this happened and so would be much more keen to make sure long tail risks are taken care of.
With SAAS it's difficult to persuade people that we need to pay for a third party backup service when the SAAS does their own backups for free.
Regarding privacy or trade secret risks, Google provides adequate permission mechanisms for that if operated correctly. For example, HR have their own shared drive which other users can't see. Threats like Google itself getting hacked or deciding to look at our docs are basically in the "act of God" category for our business.
