Description
Couchbase Version: 6.6.1-9213
Scenario:
1. Took backup of sample bucket beer-sample , Item Count: 7303. |
2. Edited the bucket settings, enabling flush + changing evictionPolicy from valueOnly to full, |
3. Flushed the bucket, |
4. restored the backup with --enable-bucket-config flag, |
5. Flush was disabled + evictionPolicy changed back to valueOnly,Item Count of the bucket after restore: 2390 |
Expected Behaviour:
- All Items are restored successfully.
- Failed Mutations count displays actual number of failures if any.
Observed Behaviour:
- All items were not restored leading to data loss.
- The failed Mutations count is not correct.
Error: Error restoring cluster: EOF
