Restore from backup

[Dragan Jotanovic]

Did anyone try to restore kvrocks database from backup created with BGSAVE?

I tried using "ldb" tool from rocksdb, with:

./ldb restore --db=/data/kvrocks/db --backup_dir=/data/kvrocks/backup

but I get:

Failed: NotFound: /data/kvrocks/backup/meta is missing

The backup file contains:

/data/kvrocks$ ls backup/
000021.sst  CURRENT  MANIFEST-000022  OPTIONS-000025

So there is no meta file. Is there a step I'm missing? Is there any other way to restore backup generated with rocksdb?

The LDB tool was built from master branch of https://github.com/facebook/rocksdb

Thanks,

Dragan

From the Kvrocks 2.0, we use the checkpoint as backup, so for the checkpoint restore, can just replace the dir with backup.
