How to schedule a weekly repeating Full and Diff backup routine.

[k^2]

For the life of me cannot figure out how to accomplish the following automation.

I want to create and schedule a full backup of a partition Weekly and then schedule a differential backup for the next 6 days. Then repeat on subsequent weeks.

The first week seems to go fine, but the second week a new Full is created but the change backup is hard coded to reference week 1's full. As the "base file" is explicitly referenced all subsequent Differentials are from the first week full and do not roll forward to the subsequent weeks full backup.

I have searched forums and tried to find an answer in the manual, but failed to be enlightened.

Can someone point me in the right direction?

For reference here are the commands created for scheduling.

Full:

start "" "C:\Program Files (x86)\TeraByte Drive Image Backup and Restore Suite\imagew64.exe" /wait /b /d:w2@0x3 /f:"E:\Backup-w2-0x3-$~YYYY$-$~MM$-$~DD$-$~HHMM$" /opw:
AF8B84A7A2B2F483F7AD83F2B9A795EB9BAB94F18BB1B2F59AF0B9A489A0B7E483B7FB96A35 /v /hash /usemd /enc:3 /rb:8 /desc:"Full Backup of Kim's Data disk D: (HD2) partition, Faster Change only, hash files, encrypted, validated, shut down on completion. Scheduled once a week at 22:00 every Sunday. "

Differential:

start "" "C:\Program Files (x86)\TeraByte Drive Image Backup and Restore Suite\imagew64.exe" /wait /b /base:"E:\TeraByte_TBI_Backups\Backup-w2-0x3-2025-07-09-1024" /f:"E:\TeraByte_TBI_Backups\Backup-w2-0x3-chg-$~YYYY$-$~MM$-$~DD$-$~HHMM$" /opw:AF8B84A7A2B2F483F7AD83F2B9A795EB9BAB94F18BB1B2F59AF0B9A489A0B7E483B7FB96A35 /v /hash /usemd /enc:3 /rb:8 /desc:"Changes backup of Kim's Data D: (hd2) partition to Backup Data E: (hd0) Terabyte_TBI_backups folder, hash files, faster, encrypted, validated, shut down on completion. Run daily Monday to Saturday at 22:00. Not sure how this moves forward to next weeks full backup."
