Summary:
When Time Machine backs up to a NAS, it will often get corrupted and prompt a message saying, “Time Machine completed a verification of your backups. To improve reliability, Time Machine must create a new backup for you.”
This script fixes that issue so that Time Machine can continue using the existing backup.
Instructions:
- First mount the backup drive share so that the sparcebundle is accessible.
- Make sure the script has execute permissions: chmod +x fix_time_machine.sh
- Run the script: Usage - fix_time_machine.sh /Volumes/[BackupDrive]/[SparceBundle].sparsebundle/
