  1. Is the pool you are copying to duplicated? If so then you will need more SSDs because DP will want to write multiple copies right away.
  2. Yeah, so I agree that it is very likely that a 1600W PSU will be way overkill. A good indication of what OP wants to run off of the PSU would help providing a bit more specific advice. @billis777: 1. Yes, you can connect more HDDs with splitters 2. I would advise to try to divide the number of HDDs evenly over the seperate cables coming from the PSU if you connect more than 16 HDDs, but that is just a to be sure thing. AFAIK, 5V is all one rail whereas 12V is sometimes divided between various rails (not in the EVGA case it seems but with my Be quiet straightpower 11 750W it is). 3.
  3. I guess it would also help if you could tell what is is you ant to run off of the PSU. The guidance by PocketDemon seems sensible but it does depend on the usecase. As a side note, I *think* that if you would be running many SSDs, then the 5V rail might become an issue as SSDs, AFAIK, fully run off of the 5V rail as opposed to HDDs which run off of the 12V rail for the motor and 5V rail for the electronics. Another thing: Do you already have the 8TB Archive HDDs? If not, then why would you choose those. I have some experience with these drives but when I bought them (early 2015) the
  4. There is no database in DP so if files were lost there is no telling which (unless you have a file listing / database yourself somewhere). However, no files that were duplicated should be lost.
  5. Yes, sorry, I did not actually look at the specs.
  6. One thing to note is that a PS may be able to deliver 1600W but that typically does not mean you can get 1600W at any voltage or rail. You need to look at the specs of the PS combined with the HDDs as PocketDemon did. How many HDDs are you looking to connect?
  7. No, don't remove in the GUI. That would cause DP to try to move files off of the HDDs. You do not want to change your Pool at all, you just want to migrate it to a new environment. So: just do my new Windows HS install, install DrivePool and then physically re-connect the drives? -> Exactly right.
  8. In this case, it is a physical disconnect. It is not really neccessary but it ensures that you do not accidentally select a Pool HDD to install the OS on...
  9. Hmmm, with that I can't help you I'm afraid. I am sure you run scanner as well. How are the HDDs connected? Do you keep a log of the errors the drives throw up?
  10. OK. Now I am not sure but... If you shut down, physically remove the bad HDD and power up, then I think DP would complain about a missing disk. If you then remove it through the UI it should be instantaneous. Then a re-measure would show that some files are not duplicated and DP would correct that by itself. Failing that self-repair, you might want to look at robocopy. I am pretty sure it has a parameter that ensures the files on the destination will not be overwritten.
  11. Yes, that is how it would/should work, especially if you have Scanner as well. I am not a Clouddrive user so I am unsure about performance in the sense that once a drive goes bad, DP wil have to check both Pools (W: and Z:) to see which files are duplicated or not.
  12. Why would it have to start over? Surely 92.3% is already moved to other disks? Do you have duplication?
  13. AFAIK, the cheaper may support up to 256 sata devices but you will need some sort of expander card. I think you just need to ensure that the card comes (or is upgraded to) HBA firmware as opposed to RAID firmware. I have a IBM 1015/DELL H310, which is a LSI SAS 9208-8i I think. 2nd hand, seller loaded it with HBA firmware for me. Just runs out of the box, no issues at all. One thing to check is, if the card is passively cooled, you may want to screw a small fan on top of the heatsink (screw goes between the fins) as these are made for servers with lots of airflow and they tend t
  14. So I assume you not only physically added the 2 new HDDs but also added them to the Pool. No need to turn balancing off. Just remove, through the GUI that is, not physically (yet) the failing HDD. DP will then move the data off of the failed HDD to the extent possible. DP will also check whether all files are still duplicated and, if not, create a duplicate. So in general: 1. Add new HDDs to Pool 2. Remove (UI) the old and unwanted HDDs. 3. Assuming 2 went without issues, physically remove old/unwanted HDDs. As simple as that.
  15. The only thing it could help you with is with the occasional write but seeing as your network (I assume a Gigabit nw) is almost saturated, even there the benefit would be small. So no, my take is don't bother.
  16. Actually, DP does not know what was on a disconnected disk. There is no database or anything.
  17. You're welcome. Once you added new HDDs to the Pool, you can start removing (through the UI that is, physical removal comes later :D) right away. You are going to replace all 8 HDD's, filled at 50% -> 16TB to transfer. And you will incur addional I/O due to the balancing. Come to think of it, once you have added some new HDDs to the Pool, it should remeasure and, possibly, rebalance. There is an X to the right of the bar. Press it. It will leave files where they are, which is good for now. Then remove (through UI) the first set of discs and, if you have more new TB than required,
  18. Actually, cloning is not best practice. Christopher has mentioned a number of times that DP does not deal with cloned HDDs well. Wrt. stopping the service and moving the contents of poolpart folders, this makes, to my mind, sense only in the case where you move files on the same HDD. Cases could be (a) you have data on a HDD that is outside a Pool while the HDD is part of a Pool or (b) when you start hierarchical pools and want to move from a lower level to a higher level pool. In your case, it depens on whether you have additional ports available. If you do, connect as many new HDDs
  19. One Pool Scenario: If a 10TB HDD fails then you can only store 6TB duplicated. This is because duplication requires both/each duplicate to be stored on a different physical HDD and after 6TB (duplicates on both 3TB HDDs and the 10TB HDD) you have no duplicate space left. Wrt Backup, yes. All data is stored in in plain NTFS format and I indeed backup one set of underlying HDDs. I run Windows Server 2016 Essentials and use Windows Server Backup. Not everyone is a fan but it has as yet never failed me (and I have had to recover). On your scenario, item #4: No. What you need to understan
  20. AFAIK, yes. It certainly did when I moved from 1.X to 2.X.
  21. If your Pool has duplicated data then you must have turned it on for the Pool or individual folders. Just turn it off and DP will unduplicate.
  22. You can create one Pool with the 4 HDDs and have x2 duplication (although, if one of the 10TB HDDs fails, then you could run into the issue that the Pool can not provide x2 duplication anymore because there is only 6TB of other HDDs remaining). Another way of organising things is to create two Pools of 10TB+3TB each, no duplication and create a third Pool consisting of the other 2 with x2 duplication. One reason to do it like this could be if you want to run a backup solution that does not run (well) of a virtual disk (which is what any Pool is) that does not support VSS. Moreover you are
  23. What is really strange is this: 1. I had a few unexpected shutdowns (no UPS). 2. Scanner had forgotten everything about scan history, ignored SMART warnings etc. 3. I just swapped a backup HDD and of the now inserted backup HDD, Scanner does remember that its last scan was 13 days ago...
