2 pointsExcited to report that I got my Retrospect backups fixed now as well !! So, disabling the "Save space and download files as you use them" setting did not work for me. So in addition to that, I tried disabling OneDrive altogether (Unlink PC/account and then remove the entire OneDrive folder) and then linking my account again which then again downloaded all files. The next Retrospect scheduled (proactive actually) run then succeeded with 0 errors or warnings ! This worked now on 2 machines already, so will try kids laptop next, but pretty confident this will work as well. Thanks to the folks active in this thread !
2 pointsOk, I did some additional debugging and I found the issue: It's OneDrive. OneDrive has an option (don't know if it's new with 1803) that gives you the possibility to only actually download a file from OneDrive to your computer if you actually use it. All files in the OneDrive folder are shown as being present, but they are not actually physically present on your computer. So they are some sort of link. The explorer shows a cloud symbol with these files. As long as one such link is present on the drive (even if it is in the Recycle bin) it will cause the -1103 error. Scanning will be interrupted as soon as the scan engine hits the OneDrive folder. On both machines I turned the option off in OneDrive settings, which caused all OneDrive files to be downloaded to the computer, and both are backing up properly now, without errors. Also checked the machines that never showed the issue, they all have this OneDrive option set to off.
2 pointsOh well, #sigh I have a few Macs. All on WIFi All on DHCP They have to be this way, because they roam from office-to-office, client-to-client, home-to-work-to-home ... like laptops do. The error -530 and associated -519 has be around in almost every version of retrospect I have used for the past 20 years. I can never find the solution, apart from a full client reinstall, and I can not be doing that every week TBH! Is there ever going to be a stable answer? Each Mac, Client and Server has no firewall or anti-virus FYI. The fixed desktop Laptops that do not leave the office have no issues. The laptops returning to the office login automatically to the WIFI and have no network issues for everyday work; email, www, ftp, server shares, printing ... what so ever. Server: Mac OSX 10.11.6 Client: OSX 10.12.6 Retrospect 13.5 Please don't say 'upgrade to the latest version of Retrospect or I may have to slap you :-) That has never been an answer to this issue.
