public function backup_migrate_destination_dropbox::file_cache_clear in Backup and Migrate Dropbox 7.2

Same name and namespace in other branches

1. 7.3 destinations.dropbox.inc \backup_migrate_destination_dropbox::file_cache_clear()

This destination updates the cache in a smart way. Normally, the list of (remote) files is created and cached in these steps:

• Create list in list_files() and cache it for 1 day.
• Clear cache on expiry, save a new backup, remove an existing backup, and refresh (admin/config/system/backup_migrate/backups?refresh=true), but not on settings form submit.

We do this as follows:

• Create list in list_files() and cache it for 32 days.
• Clear cache on expiry, change token, change path, and refresh (admin/config/system/backup_migrate/backups?refresh=true).
• Update cache on save a new backup, and remove an existing backup.

So, refresh should only be necessary when the Dropbox folder gets updated outside Drupal Backup and Migrate.
