How to backup

Full backup

Use bgsave command to trigger Kvrocks to generate a backup, and use rsync tool to copy all files of backup to remote server.

Incremental backup

You can try use incremental backup if your kvrocks database doesn't be changed quickly, this way could use less network bandwidth.

This solution is similar with kvrocks resuming broken transfer based files on full synchronization. Firstly, you should get old remote backup files list and current new backup files list; Secondly, by comparing them, you will know invalid files of old remote backup and delete them; Finally, you only copy files that old remote backup doesn't have but new backup has, and store into remote server.
