Hi @sanjeev1678 !
The new 1.26.5 version implements a new cancel backup endpoint:
Previously you could solve this by restarting Weaviate server, that will reset all backup processes.
This is not yet implemented on new client version, but you call this API directly.
here is the part of the openapi spec for that:
You need to do a DELETE call to this endpoint:
GET/backups/{backend}/{id}
Let me know if this helps!
