Closed axiangcoding closed 6 months ago

axiangcoding commented 6 months ago

Current Behavior

when i exec command

./milvus-backup create -n my_backup
./milvus-backup restore -n my_backup -s _recover

data seems like restore as expect, however, index will missing in the xxx_recover, and xxx_recover can't load in to memory. image image As we can see, vector's index is missing and can not loaded.

Expected Behavior

xxx and xxx_recover should be exactly the same, including indexes.

Steps To Reproduce

As i describe above.

I just find out restore command support --restore_index flag. and this flag works fine. I recommend adding this to the example code, it helps
