Helloe HK,

/data, /data/col1, and /data/col1/backup directories cannot be deleted or renamed on Data Domain.

The /data/col1/backup directory is the default destination directory for compressed backup server data. Clients, such as backup servers that perform backup and restore operations with a Data Domain System, at the least, need access to the /data/col1/backup directory.

Yes, we strongly recommend that do not delete /data/col1/backup directory even it was empty.

You're welcome~

Hi Leo,

Thanks for you reply.

I am asking was because we had been migrated from Directory to Mtree completely.

The /data/col1/backup Mtree was empty and no longer use.

So this is no good to delete even it was empty?

Thanks,

Yan

OK, understand, thanks.

Do we need to stop the ddboost services if we want to rename any mtree that we created manually, not the default one?
