Thanks, Nigel. I've been thinking about getting a NAS, but so far can't justify myself getting one. The AVM router's NAS was convenient, but quite slow (max throughput ~5MB/s). My current backup arrangement using TimeMachine doesn't require a NAS.

Thanks, Nigel. I hadn't, but adding it didn't help either. By using mount -t smbfs, I can see unequivocally that it's an authentication issue (using a guest mount of the same server/share specs works): mount_smbfs: server rejected the connection: Authentication error My /etc/nsmb.conf now contains: [default] port445=both signing_required=no minauth=none According to the Mac nsmb.conf man page, port445=both and signing_required=no are defaults anyway. BTW, I rebooted to make sure that /etc/nsmb.conf was re-read. Is that necessary?

Thanks. Doing that (I'd in fact already tried it when I first installed Catalina) allows me guest access to the NAS, but not authenticated (Registered user...) access. Whenever I try, , the Connect to Server popup shakes and does nothing, not even an error popup. It doesn't seem to make any difference whether I use the smb: or cifs: protocol name.

Thanks, Dave. I'm afraid I've long since given up on Retrospect and I now use Apple's TimeMachine for my backups. Now that we're running Catalina on our Macs, the NAS I was using (which can only do SMB v1 - don't ask) is no longer accessible from the Macs anyway.

David, thanks for the clarification. I've set my gender in my profile.

I use Retrospect Client. I back up a second Mac to a Retrospect server on my Mac, and I run Console on the same Mac as the server. But unfortunately for any testing, the other Mac doesn't (and can't) run Catalina. It's a Early 2011 MB Pro. But anyway, I'd have thought that the problem with the icon in System Preferences would show up whether Client was in use or not, even if it is the same icon as the one used in a Client's menu bar. My preferred personal pronoun is "he"

I've recently got a new MacBook Pro and I've gone form MacOS 10.11.x on my old MacBook (mid-2011) to Catalina 10.15.3. I was already running Retrospect 16.6.0 before I upgraded. Retrospect was transferred onto the new Mac using Migration Assistant. But I have a minor, possibly only cosmetic problem. In System Preferences main panel, the Retrospect icon is overlaid with some other strange icon (or perhaps the icon has been munged). I think it's being overlaid, because when I first open System Preference, the correct icon seems to be there initially, but then get overwritten. The icon in System Preferences>Retrospect is OK. The overlay isn't the "you can't run this" overlay that gets put on top of 32-bit apps in Catalina. This is the icon: I've re-installed Retrospect in case the icon was a glitch in Migration Assistant, but it didn't change the icon.

OK. The copy finished and I got around to testing the copy. I can navigate into the copied directory for a Verify, but when I select the data member, it goes straight back to wanting me to Choose Media again, without putting anything useful into the log. Also, very oddly, when the top level directory of the copy is called "NewRetro", I can navigate in the directories inside it, but if I rename it to "Retrospect" (the original name), I can no longer navigate inside it. Also, When the old copy is renamed from its original name "Retrospect", to "OldRetro", I can navigate into its directories, but a Verify of its members fails in the same way as the Verify of the copy. Looks like I'll need to set up new backups.

I tried doing a partial copy of one of the disk media sets, and it seemed to be accessible from Retrospect. I'm currently doing a full copy of both disk media sets. It's s.l.o.w. I'll let you know how it goes. Thanks for the suggestion. It's still no clearer why two long-functioning media sets decided to "disappear" from retrospect.

OK, I tried making a new backup into a directory that Retrospect had newly created on the NAS, and it all worked just fine. I then renamed that directory to the name of the original backup top level directory and moved the backup set directories into it, but still no good. I think I'll abandon the old backup sets and create new ones. All a bit annoying.

Thanks for the suggestion, but from Retrospect>About: "Version 16.1.2 (102)". So no luck there. Nigel, thanks for your suggestion. I haven't had time to try it out yet, but I will. I may also try moving the existing backup members to another directory on the NAS, too. The NAS doesn't have much in the way of permission control. Only registering users with passwords, specifying the name of the directory subtrees that are exported to them and whether they have read or write permission. The NAS feature of the router seems to have been a bit of an "oh, look, there's room for Samba, so let's put it in" effort. It was removed a while back for space reasons, but there were enough user grumbles that they found space for it again.

Since installing 16.1.2, I haven't been able to do backups to disk media sets on a NAS. Now, when the backup wants to start writing to the media set, it goes to Needs media, and when I use Choose Media..., I can navigate down into the top levels of the NAS filesystem, but when I get to the directory that contains the top-level directory of the disk that contains the media set members, I can open and display some directories, but not the Retrospect directory that contains the backup members. I get similar results when I try to use Verify on the backup set, or to create a new backup set on the NAS. I can access the directories where the Retrospect stored the media sets in Finder (as myself) and by using U*ix commandline access to list the directories both as myself and when su'd to root (which RetrospectEngine runs as). This all worked for several years before I upgraded to 16.1. Anyone have any ideas? Retrospect for Mac 16.1.2 (102) MacOS 10.11.6 (Please don't suggest that I upgrade - my Mac is a MacBook Pro 13-inch, Mid 2009, and this is the most recent MacOS version that runs on it) NAS: SMB shares served from a Fritz!Box 7390 router (yes, it's slow, but it worked until the Retrospect upgrade)

Has anyone tried using a Pioneer BDR-XS06T Blu-Ray drive (or any close relatives) with Retrospect on a Mac?

  I think that one means that there are bits missing in a block-wise incremental backup. I've seen a similar problem before in an earlier version, the last update to v13, I think.

I thought it would be that way.
