16 hours ago this is physical backup which make hard links (not copy)
this is not allocate extra disk space until original files deletion after background parts merge or mutations
after creation a local backup you could move it to /backup/
look remote_storage: custom examples in https://github.com/Altinity/clickhouse-backup/tree/master/test/integration/rsync and https://github.com/Altinity/clickhouse-backup/blob/master/test/integration/config-custom-rsync.yml#L21-L25
Can I use clickhouse-backup to avoid backing up to the data directory and customize the backup file directory instead? For example, can I back up to /backup?
