  1. Hi, Currently using Retrospect 9 (MacMini running Mavericks) to backup 10Tb Raid6 NAS (will be doubling if not trebling storage capacity in near future) and 5x clients using 2 separate backup cycles (8-week recycle + daily incrementals) to 2 separate external firewire 800 drives on a weekly rotation. NAS and clients connected with 1Gb ethernet. Recycle backups start at 6:00pm on a Sunday and are not finished when the company users come in on Monday morning. Are there any improvements in the hardware/network configuration that can improve the performance without breaking the bank? An incremental backup of some 70-80Gb of data has taken upwards of 5 hours to complete earlier this morning at a rate of just 580Mb/s. Are there any settings within Retrospect that can improve the performance? Any advice on how to achieve optimum network D2D backup performance would be greatly appreciated. tia
  2. I have seen BIG improvements in the time taken to "sync" when initially bringing up the console on the Mac. Kudos to Retro Dev. Performance improvements that let me be more efficient with my time are always appreciated and welcome. Thank you.
  3. I have roughly 3 Terabytes I need to backup daily, I understand the instant scan can improve performance, but it usually averages out to the low 900MB/minute. Is there a way to improve Retrospects performance or is this as good as it gets?

  4. I just upgraded to v12 for the speed improvements. I started a grooming (matching) and I see the process is at 100% (1 hardware thread), when I have 8 in my MBP and nothing else is running. This bottleneck has existed for as long as I can remember (I use Retrospect since the Cube). It is time to make such tasks multicore, at least 4 hardware threads for Desktop. BTW, I bought Desktop originally instead of Express because it supported tape, and I think it does not now (considering going back to LTO), and I only need to backup 1 or 2 computers. Thanks
  5. I just upgraded my main server to version, and notice a dramatic performance improvement in the console on long-latency connections (through an SSH tunnel to a client server) This is a wonderful thing. It changes the connection to these client systems from a painful chore, to something I can do casually. Nice work!
  6. I just upgraded to 10.2 today, and notice that in copying a media set, the copy speed is 2-3 times faster. (!) Is this expected? Where else can I expect (welcome) dramatic speed improvements?
  7. Hi, I've recently installed version SBS Premium 7.7.620 on the SBS 2003 server and the interface is woefully slow. The application itself can take 20-30 minutes to load fully and become responsive and each mouse click on a button takes around a minute to respond. I've tried reinstalling and it seems that as soon as I activate the exchange plugin or the sql server plugin the application slows to a crawl (it seems fine when they are not activated but I need sql server and exchange to be backed up). One unusual point about my setup is that the SQL Server and Exchange Server files are hosted on a drive that's connected via iSCSI to a SAN back end, so I'm wondering if it's anything to do with that. The SAN is using the open-e.com distribution and is connected over a gigabit connection. I've tried opening the application and running the sysinternals program performance monitor but not spotted anything conclusive. One reference that keeps appearing in the performance monitor output is a reference to an SQL Server registry key that doesn't exist but I don't know if that means anything (HKLM\software\microsoft\microsoft sql server\80\tools\sqldmo). I'm not getting any error messages as such, although the interface does occassionally crash when loading, however I think that's a symptom rather than a cause. Has anyone come across anything similar or can suggest some troubleshooting next steps? Many thanks
  8. i'm wondering about grooming under version 10. as a preface, i will say that i could never really get grooming to work the way i wanted it under versions 8 (where i mostly didn't experiment much due to a variety of other problems and issues) and version 9 (where my experiments met with poor results leaving me thinking that i must be doing something fundamentally "wrong" in terms of how the program was designed to work). my simplistic starting assumption is that with grooming, retrospect should be able to work somewhat like the way time machine does in that you could allocate some storage to it, let it start backing up and it would save everything (every version, every incremental backup, etc.) until it ran out of space, and then when the allocated space was depleted, it would start deleting the oldest, unused stuff to make way for new stuff. with a modest number of machines (3-4) and what seemed to me to be a modest number of backups (roughly 2x/week for a few months), i would find that my media sets would take a really really long time to groom (like ~3-4 days) under version 9. so now i've installed version 10 and i'm trying it out. my first attempt is to groom an existing media set with 1TB of storage and a few million files. so far it's been running almost 5hrs. as with previous versions, there are NO meaningful progress indicators of any kind during grooming, which is quite frustrating (edit: see followup note below about progress reporting). but if i had to guess, i would say that version 10 does not look like it is going to provide any kind of huge improvement. the web page describing mac version 10 says "IMPROVED! Automatic Disk Grooming Tell Retrospect how many backups to keep, and it will automatically remove older backups when it needs more space on disk-based storage. This technology allows Retrospect to perform faster, smaller Smart Incremental backups forever." this sounds like exactly what i'm looking for. questions: is there something i need to do in order to see this "improved" behavior and in particular to see faster grooming? for example, do i need to create new media sets? is there some kind of first-time cost when v10 reads v9 catalogs before this wonderful new feature kicks-in? any other advice on how to get "smart incremental backups forever" w/o having to recycle backup sets and hopefully without needing multi-day groom operations?
