Backup and Recovery Goals

So I found a rather easy way to find our delta for last week. 12.52 GB. Which isn't that much. Pushed out hourly to an online storage service could be reasonable.
Now to find options..
12.52 GB = 100.16 Gb = 100,160 Mb Assuming the 30 Mb/s connection mentioned earlier (and that you can use the whole thing) = 3338.7 seconds = 55.64 Mins
OK not bad, takes about 1 hour a day at full saturation to push that to your remote site. As you said, if you do that hourly, you should be fine.

Alright @scottalanmiller, Dustin seems to really want his full backups. Am I crazy to think they really aren't needed considering he has a StorageCraft backup solution?
I know this is a point of difference of opinion between Dustin and I.

Which can be done at night. Kick it off two hours after people have gone home and you are good to go.

Weekly fulls? No, not needed.

@Dashrender and @scottalanmiller how should I backup my VM's then? What is the restore process for if a VM takes a dive and I have no full to recover from?
The backup process has to remain someone current.

StorageCraft creates synthetic full backups from the incrementals. Veeam, Backup Exec, Unitrends, etc all do this.
You mount the date/time of the restore you want to perform, and say - do the whole enchilada.
-
I'm not familiar with StorageCraft specifically, so I speak about AppAssure.
With AA I boot from a CD in the VM I want to restore to. That image finds my AA server on the network, I authenticate then choose my restore point, and tell it to restore the whole thing.

It could be, but if he's extra paranoid, or just wants to make sure the sync is more than once a day, he can kick it off hourly.
Assuming the typical work day (for production of files) you're dividing that hour into 9 chunks, so it should take around 7 mins at full speed, probably more like 12 at not full speed.

You have a full ready to go that is older, say monthly, and you apply the delta to it. Instead of incrementals, move to differentials. All you need is the full plus the differential. Inrementals mean you that you need EVERY incremental to do a restore. Differentials mean you only need the Full plus the latest Diff.

But you didn't mention that StorageCraft is what has that full. I say this just to be clear.
@scottalanmiller Does Unitrends ever take a new full backup as a matter of standard practice? (I'm not considering issues where there might be corruption or something that causes you to need another full backup)

Yes, regularly.

I can still run this full monthly with a tool like NAUBackup and a Crontab job. That is where I'm considering the fulls from coming from.
The incremental backups would be built from Storage Craft and for file level restore.

But does breaking this appart from StorageCraft actually make sense? Assuming you're a Unitrends shop you typically wouldn't do that. You'd have Unitrends do everything.
-
Can Unitrends build a complete backup that can be imported to a Xenserver should the Guest VM get corrected?
-
And does it have to run on a separate server to create that backup file?

Not sure what you mean. Unitrends handles every aspect of XenServer.

It would run as a VM. VMs have no means of knowing if they are local or not.

i agree. Find one tool that does the job and stick with it. Trying to use two separate tools is making this incredibly complex and complexity is just another term for risky.
-
I'm just a bit confused on how it would work, as I haven't use StorageCraft on XenServer, and I'm thinking of it just like "trying to format a windows partition
that you're using to run the command from" -
Or I guess the better way to explain it.
How do I restore from Storage Craft if I want to simply dump a corrupt VM? Does it build a .xva, .ova, or vhd backup?
