can't create backup with mkdir /mnt: read-only file system about clickhouse-backup

[AlexAkulov]

Try to create /mnt/data1/clickhouse/backup folder manually.
Make sure that you run clickhouse-backup from root or clickhouse user it is necessary for files interaction.

@jsding Have you solved this issue?

Hi, AlexAkulov,

Thanks for your attention.
Not yet, I run clickhouse-backup tool on other machine.

Can I create backup folder on other directory? Worring creating directory in clickhouse data will corrupt the database.

[AlexAkulov]

Change of 'backup' directory is not supported now.
You don’t have to worry about this. Many people created '/var/lib/clickhouse/backup' directory and no one lost the data.

@AlexAkulov Does changing the destination folder still not supported? We use AWS Lambda to backup clickhouse and only /tmp folder is writable.

@empeekdev you can't use clickhouse-backup with AWS Lambda
cause clickhouse-backup require direct access to clickhouse server /var/lib/clickhouse folder for move hardlinks from detached to /var/lib/clickhouse/backups/<backup_name>/db/table/
