The Backup and Migrate module is not currently supported on Acquia Cloud for several reasons:

• The module has a negative impact on the filesystem.
• The module can cause performance issues as it hits the active database (rather than the passive).
• Structural issues can occur in the database when only certain tables (rather than the entire database) are copied across. Backup and Migrate allows you to choose a subset of your database tables.

Acquia suggests that you use one of the following alternate methods instead of the Backup and Migrate module:

• Use the Cloud UI

  In Acquia Cloud interface, Select your app > Select the desired environment > Databases, and then click Backups.

  • This method avoids the performance issue by using the passive database.
  • This method ensures database integrity by copying the entire database rather than certain tables or rows.
• Use rsync for files and backups
