    Use the same disks for multiple pools

    Not quite when you use the wizard. If you select to grant access to specific people, the default is no access at all. Not sure how you would create a shared folder otherwise.

    Use the same disks for multiple pools

    It may be because I run DP on a server platform (WHS 2011), but I can control access rights for network users to specific folders that are in the pool. No way a user could view, let alone modify, data outside of those folders.

    check-pool-fileparts

    Yeah, it would be great if the was an option to have the output in CSV or, my favorite, pipe-delimited format. Just needs a record type identifier in the first column.

    Running out of RAM

    Although Process Explorer is a great idea, I find that Resource Monitor, which comes with any Windows installation AFAIK, is easier to use and helps identify such issues rather often already.

    Balancing as a Backup

    Julius, I am 48 and have been using tapes and disks to store data since 1982 (Tandy TRS-80 Model III). Yes, DP may save you from HDD failure due to its duplication but that is about the only fail-safe it provides (same as RAID and I agree on the recovery issues with RAID. DP is, to my mind, far easier at the expense of additional space (compared to RAID 5/6)). Yes, a good backup policy can be cumbersome to implement and, especially, adhere to. Nevertheless, modifications, deletions over the network (as Christopher said, no recycle bin then), fire and theft etc. are not covered by DP. It may be that it is safe enough for you but I would never advise that DP is good as a backup. In my case, I run WHS2011 (will move to WSE someday), with DP x2. I also run a daily Server Backup which is scheduled and needs no manual intervention (and I could set it up to backup every hour if I wanted). The Backup HDDs are rotated offsite on a weekly basis. Can I still lose data? Sure. But at least I can restore *most* at all times. An alternative, of course, mught be the cloud. For example, DropBox retains all versions if you have a professional subscription (including deleted files) and it is offsite at the same time. However, I do not like the cloud personally. Edit: Ransomware! I forgot to mention ransomware.

    Balancing as a Backup

    No. If you have x2 duplication and you save a file then it will be duplicated instantly. If you delete it, both duplicates are deleted instantly. Balancing is the procedure by which the usage of the pooled HDDs is made to comply with the balancing rules. As an example. DP writes, by default, to the HDD with the most space available. If you have two HDDs with equal space available and data gets deleted from one of these then balancing would fill it up again. A simple advice: Do not assume DP has anything to do with backups. It does not. It helps you increasing uptime and easing recovery in case of a HDD failure (assuming you have at least x2 duplication and not 2 HDD failures at the same time or during recovery) and allows for a BFVHDD (Bif Fing Virtual HDD) but that is it. For backups, that is copies of files which protect you against HDD failure, system failure, fire and theft etc., look for real backup solutions. If, for instance, you are running a server OS, use Server Backup for instance (and rotate backup HDDs offsite).

    One difference is that if you accidentally delete a file, it will be gone. DP is _not_ a backup and you're setting yourself up for trouble when trying to use it as such.

    What constitutes "Other"?

    Hmm, I don;t get that first pic. It mentions DrivePoolDisk1 and 2 as Pooled but also als non-pooled below? Are drives these mounted as folders or something? What is also weird is that the Other on both appears to be equally sized, something I rarely see in Pools.

    What constitutes "Other"?

    Do you run server backup? Server backup can leave stuff in sysvolinfo, terribly annoying, but it tends to clear out when space becomes limited. There was a time that I was OCD enough to try and empty it all out but it is always a pain with first not having access rights (which infuriates me to no end, it's my own goddarn HDD!), then having to take ownership and even that failing. But generally, AFAIK, there is no need to worry.

    How to get drive pool to honor my new placement scheme

    Actually, no. One copy would be on D1 to D4, the other on D5 to D8. This is because Pool W will regard Pool U and Pool V as single HDDs and never place both duplicates on only U or ony V but rather one on U and one on V. If you then use the optional Ordered File Placement plug-in, you would fill D1 and D5 first, then D2 and D6 and so on (this does assume that D1 is od equal size as D5, D2 as D6 and so on). Some organise otherwise with the File Placement Rules. I wouldn't know but it may require that you offload data first indeed. But the question remains, why bother?

    How to get drive pool to honor my new placement scheme

    Couldn't you use hierachical Pools for this? 1. Set-up Pool 1 (say U:\) with HDDs D1 to D4, no duplication, file placement as desired 2. Set-up Pool 2 (say V:\) with HDDs D5 to D8, no duplication, file placement as desired 3. Set up Pool 3 (say W:\) with U:\ and V:\, x2 duplicattion. Done! Having said that, what do you mean by "go hunting thru 8 disks to find a file should the pool break"? If it is about one HDD failing then ypu do not need to sift thure disks as DP would re-duplicate the files that were on that HDD for you, for free and automativally (once you have removed the failing HDD from the Pool and provided you have sufficient space). And for that scenario, 1 Pool of 8 HDDs is better even.
  12. DP has offered hierachical Pools since rencently, version 2.2.0.744 or so. If you're on an older version you'd need to update. Not sure if there has been a stable release already with this feature. I am running .746 BETA (an early adopter exactly for this feature).

    Drive suddenly missing!

    Ah OK, my bad. Thought you meant that was my recommendation (to move out of Pool first).

    Drive suddenly missing!

    Well I am happy all seems fine now. But where did you read you should get this drive out of the Pool as a first move? I would, as I said, only consider that if the Pool was fully duplicated. I am doubtfull about Server Backup being the cause and I would turn server backup off when hell freezes over. My guess is a bad cable or cable that is loossie. But who knows...

    Drive suddenly missing!

    Well, if everything was duplicated, you could have removed the HDD in DP, even if it was missing already, add another HDD and have DP rearrange and reduplicate everything. If you can read from it in another machine then making a quick copy of the files is never a bad idea but... are they not also on your Server Backup? If you want to feel secure, sure, make a copy. Now let's assume you make that copy and the HDD then fails. You have all your files but I am not sure how to efficiently put it all back into place. My guess would be to: 1. Add new HDD to Server and Pool 2. Stop the DP service (not sure if neccessary) 3. Copy all the files from the failed HDD, so now present somewhere else, to the hidden poolpart folder on the new HDD. 4. Start the DP service (only if you did 2) 5. Let DP do its magic. You may want to press re-measure. I would hope that DP manages everything for you but WARNING I am not sure. Christopher would know...
