请问tidb br快照备份–storage后面location是什么意思?感觉不使用这个location也可以备份。
但是备份日志的时候又不能使用localtion,百思不得其解。
[tidb@monitor ~]$ tiup br log start --task-name pitr --pd ‘192.168.1.183:2379’ --storage “location:///backup/log-backup”
A new version of br is available: v8.3.0 → v8.5.0
To update this component: tiup update br
To update all components: tiup update --all
Starting component br: /home/tidb/.tiup/components/br/v8.3.0/br log start --task-name pitr --pd 192.168.1.183:2379 --storage location:///backup/log-backup
