Usage

DO BACKUP YOUR DATA FIRST!!!

repair db

leveldb-tools -dbpath /path/to/leveldb -action repair

this action will rebuild each .ldb file.

---

import db

leveldb-tools -dbpath /path/to/leveldb -action import -file /path/to/dump.file

---

export db

leveldb-tools -dbpath /path/to/leveldb -action export -file /path/to/dump.file

iterator through the whole db, and dump all the key/value pairs to file.

---

export db(force)

leveldb-tools -dbpath /path/to/leveldb -action export2 -file /path/to/dump.file

try this action if action=export not work.

this will scan all .ldb file,and dump key/value from each .ldb file.

But there are some shortcomings:

1. Not 100% of your data will come back,but at least most of them.
2. If you update some key frequently, there may be multiple values under the same key in Level-0 tabel file.
   I try to use the latest value.
3. because of (2), some deleted keys may be "come back".
