Hi, yes, I use this kind of setup on two Windows 10 machines using rotating HDDs.
These are (hopefully) swapped once a day and the (almost identical) backup jobs start with a time offset of 10 minutes looking on several drive letters for “their” backup HDD medium.
The machine using HotSwap HDDs gave me some headaches since it seems that these HDDs are to expected in the same slot by Windows 10. The system using the same kind of configuration on external connected USB HDDs which most the time works fine.
Best to show you - here are the (anonymized) settings of backup job #6 for HDD nr. 6:
{
"Filter": "",
"Name": "--alternate-destination-marker",
"Value": "DupBack6.txt",
"Argument": null
},
{
"Filter": "",
"Name": "--alternate-target-paths",
"Value": "e:\\DupBack;f:\\DupBack;g:\\DupBack;h:\\DupBack;",
"Argument": null
},
The full (anonymized) settings:
