Description

Bug Report

What version of Kubernetes are you using?

What version of TiDB Operator are you using?

What did you do?

Configure scheduled backup with maxReservedTime 7d

What did you expect to see?
Backup before 7 days ago are cleaned by GC.

What did you see instead?
Backup is not cleaned because 7d is an invalid option:

E0622 23:02:46.534601       1 backup_schedule_manager.go:277] backup schedule prod/tidb-backup-e7ncrgbu, invalid MaxReservedTime 7d

Research direction

Start by locating backup_schedule_manager.go and the MaxReservedTime validation that emits the reported error. Trace which duration units are accepted, then run the relevant backup-schedule tests or add coverage for 7d; done means scheduled-backup garbage collection accepts day-based retention without the invalid-option error.
