Kusama Pruned RocksDB (1000)

Note - These backups have only been tested on recovering the RocksDB Kusama databases (ksmcc3) on a Kusama node. It is not intended to be used on any other node or in any other way than described below.

IMPORTANT: These should only be used for testing purposes. For production, the best practice is to sync your node over the network from beginning. Only recover from backups off of a private backup copy which you have created (CertHum does not use these backups and recovers from private copies.) These backups are NOT endorsed by any 3rd party.

These should be only restored in the following directory (do not alter directory path):

/home/polkadot/.local/share/polkadot/chains/ksmcc3/db - for the Kusama Archive RocksDB
Tested on Ubuntu 18.04
Pre-req – zstd.

Recovering this backup to any directory path other than the one provided above will impact crash consistency and potentially corrupt your database on process failure resulting in financial loss.
