The restore command is used to restore an object from the frozen state to the readable state.

Command syntax

./ossutil restore cloud_url [--encoding-type url] [--payer requester] [-r] [-f] [--output-dir=odir] [-c file]


  • Restore an object from the frozen state to the readable state
    ./ossutil restore oss://bucket/object
  • Restore all objects that have a specified prefix to the readable state
    ./ossutil restore oss://bucket/path/ -r                         
    • The restore operation takes about one minute. You cannot read an object that is being restored.
    • By default, the object will remain in the readable state for one day. Running the restore command for an object in the readable state will prolong the period for another day. You can prolong this period to a maximum of seven days. After this period ends, the object returns to the frozen state.
