So @BRRABill did you get your answer from this post?

Yes, go with as slow as your business supports.

OK so this thread has covered the backup window - what about the recovery window?
Sure you have 8 hours to backup, but is your company OK with 8+ hours for recovery?

Excellent point. Recovery time is more important than backup time imho.
It can help a lot to plan backups by starting with recovery.

Right, and this has been discussed here many times in that if you have important data, it probably shouldn't be taking 8 hours to restore it all.
Perhaps a full restore is not the optimal way to restore in the case of a major issue.

if you loose a all your storage you might not have any choice. We are talking about worst case here.

Importance of the data doesn't determine time to restore,normally, but the importance of downtime. VERY different things.

My point being that if there are a few files or an application that NEEDS restoring ASAP, perhaps that should be part of the plan versus pegging 8 hours for a full backup.

Sure I suppose I can see what you're saying,
So let's say you know what files you need first, you loose the whole server, so you restore those few files first before kicking off the full restore, during which you often have to wait until it's completed before accessing most if not all of that data.
Definitely not an option when restoring an application system either.

Application system doesn't even need to be restored from backup, it can be built fresh.

The application data needs to be restored and that might be the bulk of what's actually being restored and takes a ton of time

Application "data" isn't in the application, it's in the database. That's part of the database restore, not the application restore.

This is why I use VMs, and separate the os, data, and application on different virtual disks if possible. In SQL cases, you will by default to follow best practices... Database, logs, etc on different .vhdx's, maybe on different tiers of storage, ssd vs hdd.
OS takes minutes, applications take minutes, then comes the data however you like it.
Typically those kinds of restores are relatively quick. Its usually file server data in SMBs that take forever to restore. Most SMB databases are less than 100 GB. But if the need comes to restore a 10 TB file store because the whole thing blew up, sure that will take a long time unless you have it replicated onsite or can spin it up in the cloud.

@Tim_G
RIght, that is kind of my point.
It's not feasible for me as a SOHO/SMB, but for many it might be.
A lot of times teeny companies think they need to be up 24/7 without downtime without realizing the cost.
If there are mission critical applications, perhaps they need live replication, or something such as that.

Still can work well for an SMB, a lot of those things, like separating applications from databases, can be free. Not necessarily a scale thing, can just be a better approach.

It all depends on the RTO you need to hit. But to the points being made here, the RTO may be different depending on the applications in your environment. Maybe the ERP system and its SQL database are all that need to come back within 1 hour of going down but the file server's RTO could be closer to 2 or 3 hours.
We talk about RTO and RPO, but I bet you in most places those are not clearly defined down to the VM / application level. If they are and you've planned accordingly, bravo.

I had an RTO of 4 days approved by the board for our EHR 10 years ago - I couldn't believe it when they said that was fine.

That's insane. Did you ever have to hand it back to them after a disaster? "Hey, this is what you said was acceptable, folks."

I'm just going to assume you can hit a target of less than 4 days by now.
