Catalina has been migrated to new blade SSD (if it only plays a role in this case - by occasion Mac motherboard has been replaced with one of stronger graphic card; also CPU upgrade took place).
Before migration Time Machine backups were made to two destinations: external USB drive and sparse-bundle on network share. Backups to both destinations ran independently, automatic carry out of backups was always disabled, as well as it keeps to be in this state. Subsequently to migration the inherit operation for external USB drive could be completed successfully, also associate disk operation succeeded fully in that case.
Problematic is however the inherit of Time Machine sparse bundle stored on network share.
completes with error message "Invalid target".
Network share mounts in general on the Mac with no problem - using Finder to mount. Also the same sparse bundle mounts with no problem on the same Mac - also using Finder to do the mount. tmutil however can't complete inherit operation. Its manual has been consulted to check for possible mistakes in tmutil usage, but none could be found. TM backup in this sparse bundle worked very well prior the migration of Catalina to new SSD. Sparse bundle is not mounted to Mac while trying to do inheritbackup.
I am perplexed how to look further for possible reasons and solutions.
Network share housing sparse bundle uses own credentials, inherit backup however is conducted subsequently to successful mount of network share hence different credentials should not play a role here. Account on network device housing the share has read-write access, as it was before migration. Nothing changed on side of network share, only the Mac underwent low number of hardware upgrades.
In course of troubleshooting the sparsebundle TM backup has been removed from list of targets - TM ui in System Preferences. This way the sparsebundle is no more listed in TM System Preferences as used destination. One can add only the network share as new destination, however not the existing and valid sparse bundle.
Following command fails however as well:
Network share side user executing above command has read-write access.
