Can you do incremental forever to tape? I don't believe so. He would need to hit the WAN. 8TB a day is pretty ridiculous to go over a WAN.
Why would you need to send 8 TB a day via the WAN? He'd only send the changes daily via the WAN. And AppAssure supports that type of replication.
This is why knowing the daily delta would be important.
Didn't he say the incrementals needed 8TB today?
No 8 TB was to perform weekly fulls at the current infrastructure size.
Incremental changes are likely > 20 Gb/day
-
Which if I ignore performing weekly fulls and instead perform them monthly to tape. I'll have to start looking into LTO tech has I have zero experience with it.
Edit: Well I should probably look into LTO tape anyways...
-
I think the solution really is to perform monthly fulls to local disk then to tape and take the tapes home.
Perform incremental backups using storage craft to on-site / offsite daily and dump the old versions at 72 hours. Cycling the tapes every 72 hours (3 days)
Would be easier to just keep it for 5 days though.... This way we have to swap less tape around...

Wait, if a full is 8TB, where did I get 22TB from?

Oh that's nothing. Just seed a backup device and set it remote.

Full Backup retention for an entire month.

That would be 32TB then.

Actually it's technically a 7 day swap cycle now for what we have.
Might have to keep the same process if I want to reduce IT's labor on the backup process. (Weekends count to computers)

8 TB is with growth... currently he's at just over 6 TB.
so 24 TB for a month -
@scottalanmiller Only if we we're fully using all 8TB.
We have free space on the systems now and are only using approximately 6TB of total 8TB capacity in the infrastructure.

I'm really lost - why are you worrying about full backups when you have a StorageCraft backup solution?
-
@Dashrender So if something should happen to the vDISK on XS. That we have a way to simply import a 2TB file to the server, and turn it on.
Trying to K.I.S.S

Can't you get that from the StorageCraft system?
-
Not effectively (at least with what we have).
Fulls currently take over 24 hours to generate when their needed. So fulls are almost never taken.
But our system partitions are ignored, besides 2 servers.
I want to include everything in the backup process. So everything is protected.
-
I'd say your two separate backup solutions aren't very simple. One extra thing that can fail. One extra thing to maintain/mange.
StorageCraft for daily incrementals
and home built solution for weekly fulls.Maybe StorageCraft can actually create the tapes for you?
I know when I was looking at Backup Exec it could. It would pull incrementals daily, then it could spin down full backups to tape on whatever schedule you wanted. It would create a virtual full backup at that given point in time and that is what was backed up to tape.
-
Incremental changes can be written to local onsite storage, but this doesn't include recovery options for "everything" just the system changes from the past 3 (but should be 7 days).

I might be being mean to NAUBackup, calling it home built.

It takes 24 hours to generate a full backup from StorageCraft? Why? What's the hold up?

Yeah, this seems like a major problem. If it takes that long to take a backup, what's the restore process look like?
-
@scottalanmiller We've never had to perform a full restore thank god.
But I'd imagine that it's awful.
