Synology one bad sector crashes whole volume RAID0
-
Do you have a backup or do you need the data?
I do data recovery.
-
Yeah the drives are ~$125 vs ~$260. I'd go with less backups and RAID1 over RAID0.
I have to ask why is there an $800 limit on this system if you know how many backups you need? Especially if you're forced to use RAID0 to meet the requirement of "5 full backup sets". That would seem to say "I need this much protection, what do I need to spend to get that protection in a reasonable way?"

In theory, this budget is either based off of the perceived value of the data and/or it defines their value of their data.
The "rule of thumb" for figuring this out is that you would spend around a quarter of the data value at max for protection. So if this was the sole protection, they'd see their data (that is specifically affected by this device) as having a value of no more than $3,200. Which is reasonable, it might be rather unimportant data that's just nice to not have to recreate.
-
@scottalanmiller In that scenario then you'd still have to meet the following point I mentioned just above.
What do I need to spend to protect me from a $3,200 loss? It's clearly more than the money that was spent already, I'd say by about $300.

how critical are those backups? If you needed them and lost them, do you lose more than $800?
Not that critical, at least not now. Once I start internally hosting some important data records and DBs and other LAN stuff, it will be.
@donahue said in Synology one bad sector crashes whole volume RAID0:
the cost of 2x4tb is basically the same as a single 8tb if we are talking WD red's. One drive at 8TB would be safer than 2x4tb in raid 0. You could always add the second drive and make it raid 1 later.
A year ago or more the prices were higher, not even sure there were 8TB drives at all? I think the 2TB drives were around $200 each, and the Synolgy about $400, so it was $800+ fully configured.

Thanks man, but oddly, just turning the Synology off and on again brought the stripe back to life and worked just fine until next sector was discovered bad.

I don't know how to put a price on data. I mean, let's say we lost our pile of vendor invoices. Well maybe there are 150 of these files. So if those were lost, we'd have to spend employee time tracking down all our outstanding orders, recreate the files, then track down all our own customer orders waiting on those products. So I don't know, that's maybe 4 people working for 3 days or so to figure that out. So let's say around $2000 of labor time. Plus if they are doing this work, then they aren't doing other sorts of work that may or may not translate to revenue, so maybe add $1000 for lost revenue perhaps?
This is all very speculative. Some data maybe can't be recovered at all, perhaps old reports or records.
Anyway, I didn't say $800 was the budget limit, I'm just saying that's what I spent at the time. My original plan was to push ALL my workstation backups to the NAS, which would have surpassed a RAID1 4TB mirror. Hence the stripe originally. Plus acting as backup for the server which wasn't holding anything important, I was just going to store some snapshots of the VMs.
All that to say, I never ended up putting workstation backups on it, and it became more of a general purpose network sharing NAS, and so I'm only using about 1.2TB.
You can imagine, since the NAS become general purpose, it wasn't classified as a backup device any more, but a primary device! So now it needed backed up as well. I bought a 4TB USB drive and that's when I tried to backup the NAS to the USB and it started failing and all this went down.
Here is the odd part, ONLY when the Hyper Backup tool does a backup does it start finding bad sectors. But if I use a tool like Robocopy and just copy all the files manually, no failures. What gives?

8TB released in 2014, 10TB in 2015, and 12TB in 2017. 14TB should be out with limited availability now.

As the IT guy, it is for you to give a cost to recovery, it's up to the business to tell you how much the data is worth. They set the budget, so they had already determined the value.

I appreciate the advice of enterprise IT thinking but that's just not how I've seen it in small business. The only thing small biz owners ever do is haggle about price. Waaaa no way I'm "renting" MS Office. Waaaa no way I'm "renting" Adobe CS. Waaaa no way I want to pay a monthly fee for EVERY employee!! Waaaa what do you mean we need central management of XY service? Waaa I don't want to pay for hosting!
I provide pros and cons, options, and prices, and lay out the risks. They make the decisions. I'm not the one who demands we "share" O365 accounts, that was their brilliant plan to avoid $30 more a month. I'm quite tired of it really.

Well, there are really only two choices...
The business takes the time to DETERMINE this. Or...
No one knows.
IT doesn't have the slightest power to determine the value, it's just not reasonably possible. You aren't the CFO, owner, or even the accountant.
So even in the smallest SMB, it's always the way that I said. They might see their data is "too worthless to bother figuring out", and that is very common. But one way or another, the business side is the only possible determiner of the value.

Exactly, and their responses are how they tell you how much they see the data as being worth.

It's a catch 22 though. If they decide they want to take some risk, and then bad things happen, they don't own up to it, they just attack me like "why didn't you prepare for that!"
Either way, I end up the bad guy.

I came from small business and the reason you haven't seen it that way is because small business' reasoning is terrible 99% of the time

Everything in writing. Literally. Also get out of there. They aren't paying you enough obviously.

You may want to look at your licensing for O365 and report this to Microsoft. Generally licenses can't be shared and are per user.

True, but that's the nature of not being the owner. They will never want to own up to mistakes. But whatever they do, they set the budget based on their interpretation of their own value. That's it. No matter what politics are at play, that's what is happening.
That they blame you for their mistakes is neither here nor there. You don't have the power to fix their mistakes, and it isn't directly related to the case at hand but to all cases.

And definitely not with O365. It's not a grey area at all, it's straight up theft.

Honestly if they are asking you to break the law (as is evidenced not once but twice in this conversation) you need to GTFO before you're culpable.

I have much bigger concerns in my life then worrying over whether MS is losing out $30 a month.
And I know, I've spent most of my time on mangolassi ranting about my job, lol. But the time is coming to leave, as my side business is growing and I'm ready to do my own thing. Hopefully this year, I'm out. Hopefully within the next couple months.

Why not just use everything cloud hosted for this 11 employee company? All this money, time and effort makes no sense when each user gets a TB of disk space on Office 365.
If you are really paranoid, then back up to another cloud provider. All this equipment and man hours make no sense on 11 person company. Just pay for each user like you're supposed to and you will have all the resources you need.
