I never did get into the BBS world at the time. Simply did not have the money to make it work or pay the phonebills (i.e., my parents did not). My first HDD was actually (1988?) a 20MB ST-506 in a A590 HDD and memory expansion kit which was connected to my (well, my brothers' but he did not do anything with it) A-1000. It also had a SCSI controller but those 42MB Quantum HDDs were simply way out of budget. I seem to remember that at the time there were both MFM as RLL HDDs but it's all a bit gray in my memory (sortof like the Samsung EVO-drives I guess). Good times but had I had some funds at the time, it would have been me who did google, facebook and youtube.

Oh! The US Robotics 14k4 and 28k8 modems! These were simply unaffordable over here for me, prices were not as alingned as they are today and even in the US they cost a lot of money. I was rarely jealous but for those..!

Now I am really jealous. Do you actually run them through an emulator?

That may all be true for the HGST drives but that does not apply to the Seagates. The Seagates actially come with firmware that optimises write-behaviour. It's "the other approach"  that that article refers to. There are no compatability issues with the Seagates.
 
And yes, due to SMR you may suffer write penalties but if we are realistic, you would have to have quite some heavy I/O to actually suffer/notice this. Opening a word doc, changing it and saving it? No issue. Movie editing? Not sure, perhaps. OLTP-databases? You typically simply do not want to risk degraded performance so no. But I really believe the use-cases where write performance would be an issue are very limited.
 
 
 
OK, but who writes 100TB a year (and wants to keep only 8TB of that)? 
A good review was done here: http://www.storagereview.com/seagate_archive_hdd_review_8tb
 
In the use case of OP, writing in batches of 20 to 30GB at a time, mostly to retain, these are a great deal IMHO. Oh, and read speeds are crazy.

Well, if it is an educational excersize only then I would opt for the WS10 Tech release. I have that installed on an old machine for that purpose as preperation for the migration from WHS2011 sometime in the early 2020's

Which would not help you against a number of things. I would recommend offsite backups for important data (all data actually to the extent possible).

With default settings, DP allocates to HDDs with most free space and it seems as if you have added a 1TB drive in a po with rather larger ones that are not filled halfway. It will be quite some time/data before that drive is used.

I should probably stress it with some of my SQL stuff but I don't like to spend the time right now. On my lappy I have an SSD for the DBs but I had the tempdb on the spinner. When I moved it to the SSD as well it boosted a script by 40%. Hate to think what would happen on the Seagate Archive HDDs, I imagine queue depths well in the hundreds.
 
Anyway, love the wbadmin.msc, it there something similar for client backups in WHS2011?

WHS2011 so .vhd files, not vhdx unfortunately. I'll check for a while but overall. In two weeks my WD Red Backup HDD is up in the roster, I'll take a look at that as well and compare. So far, I am happy. They may not be the best write-performers due to SMR (still unsure) but they get the backup job done it seems, I can grow my server to about 8TB in unduplicated backupable data at low cost and they read like crazy.
 
It is a ST8000AS0002-1NA17Z and the ID number is J1PO37PU

Congrats! And yes, that is one hell of a machine.

Ah yes, as an OS drive, it may well do horrible. So that leaves defragmentation and temp storage. But defrag is something that should be doable in the background, suspending in case of real I/O, I guess the FW may also do something while idle, a bit like TRIM on SSDs. E.g. writing new data to clean bundles of tracks and then re-organising when idle. Anyway, one I finally get them I'll see (and tell) how well they do as backup drives.

duelistjp, those 8TB seagates are not called "Archive" for nothing. The thing with these is that re-writing a sector may cause more sectors to have to be re-written. That's due to the SMR tech in these. I will get 2 soon but I intend to use those as backup drives, not actual server storage. On the other hand, the data on my server is mostly static anyway so it could well do the job. I'd just hate to have, say, a larger database on those.

Agreed but I am trying to avoid an Intel vs AMD fanboyz debate. Let's just say the A10 do well for a Server? I used to be an AMD fanboy and LOLled at the Pentium 4s and their heat issues. But Intel has come a long long way since then and well, I changed sides and will remain here until a better product comes along.

I've been saying for years now that everyone should have a personal copy of the interweb.

That's still twice as many HDDs as Ryo was planning to use but I see your point. Max power per rail is something that is overlooked easily, in this case by me perhaps and, yeah, peace of mind is worth a lot.
 
I was still looking at Ryou running 3x1TB and missed that he was planning on 12.

FCOL, a 1200W PSU? Get some splitters! Them's to be used with like dual X295 AMD cards having a TDP of 500W and a 150W CPU or something. I wonder what kind of efficiency they reach when you're actually drawing like 120W (10%)?
 
On the other hand, what's another 170 bucks...

About the backup. I would think that one would never want an OS to backup a database, that is something the DBMS should do itself. However, I run SQL Server on a client and the databases are in fact backed-up by WHS2011. So much so that SQL Server is actually aware of the backups WHS2011 takes. No clue what MS did there but I like it. Just to test I restored one and indeed could attach it and it was the full DB. Of course, I have no clue how that works AIW actual transactions occur on the DB during backup.
 
My point is, maybe Server Backup, which AFAIK uses VSS as well, can do the same as well.

Actually, that is what I do: 2 x 2TB Pool, full duplication and I backup one of the two. Should I need to have more memory than I'll add another 2x2TB in a seperate Pool and backup _one_ drive of each Pool.

I'd really like such an app/add in. It may be the absolute best worthless app (worthless in that it may never ever find anything) but the comfort would be so great.
 
OT: Early days I was a console operator at a Unisys mainframe (or, as the IBM-operaters called it, a mini ;-). Late 80s. Everything was double and could survive one failure: 2 CPUs, 2x5 Harddrives (huge machines), 2x2 tape drives, 2 consoles of course, 2 printers, 2 communication controllers etc. The database was duplexed as well. Every Wednesday evenening we would run the Compare. It'd check the contents of both databases. Had been done since the start in 1985, went until the system was replaced in, 1998 or so. Wednesday was overtime day (evening) because the compare ran for 2 to 3 hours and exceeded the last shift. Paid well that and was very reliable. It never ever found a thing. Everyone was happy.

Have you read this: http://community.covecube.com/index.php?/topic/37-faq-unduplicated-vs-duplicated-vs-other-vs-unusable/
 
I have never seen a DP setup with 0 "other". "Other" is not unduplicated in the sense that it is data you want duplicated. It is data on the drives that resides outside the Pool (or poolpartfolder). These may be shadow copies, files you put on there (which you obviously have not) and other stuff. The SystemVolumeInformation folder is a well know cause of "Other" becoming quite large sometimes and the another day it may have all but dissappeared.

I think the official answer is that as long as the count does not increase, you're probably OK. Now I have never had HDD issues until recently and in that short experience, once they arise, they rise in numbers.
 
I have had chkdsk /r and formating (not quick formatting) seamingly correct errors (according to Windos) but the next scan would show these again.
 
My policy now is, once I get them I may give them *one* more chance. Otherwise, my son and I love to tear them apart and play around with them. It's a bit of a thrill holding just the motor with the disks spinning at 7200RPM.

Hi,
 
In the Event Viewer that I look at on occasion, DP 2.x comes up sometimes stating that an Error report file has been saved somewhere (actually, two files at the same time). I don't actually observe any issues with DP. Should I worry and what should I do with the file? I can't actually seem to read/open it.

Hi all,
 
I have DP2, full duplication of just two 2TB drives. I need to replace one of them (rising sector allocation error count).
I could just:
1. Remove on of the drives from the pool (how would DP deal with duplication if one of the two is removed?)
2. Remove the drive from the server
3. Add new drive to the server
4. Add new drive to the pool.
 
However, I get the feeling that removing takes some time for DP to process and adding a new one may take a very long time (in background, whatever checks it does etc).
 
So, I am wondering whether it would not be quicker to:
1. Copy all data from pool to a third non-pooled drive (already present in system)
2. Delete all files from pool
3. Perform steps 1 to 4 above
4. Copy all data from third non-pooled drive to pool
5. Delete all (copied) files from third non-pooled drive.
 
The _only_ disadvantage I can see is that I would be deleting shared folders and I am not sure whether those would be reinstated (although, I could of course just delete the contents of those 12 folders).
 
Total size of unduplicated data is about 600GB.
 
Any advice?

Hi all,
 
Scanner is showing 2504 Reallocated Sectors Count on one of my drives. The message became apparent to me three days ago. The number of affected sectors has not rissen. Should I be concerned (alread)?
