Removing files in Centera after removing them from Celerra and using Rainfinity
Rainfinity manages the information stored in the secondary storage Centera and in the primary storage Celerra. If I remove a file from Celerra (that file was previously stored in Centera, so in Celerra there is only a pointer to the content stored in Centera), The file is removed from Celerra, but not from Centera. In Centera, there isn´t any retention period.
When is the file stored in Centera removed?
Thank you in advance.

In this case, as you reference Rainifinity, it is best to contact Rainfinity support directly on how to manage this environment.
In the case where the connection is Celerra -> CFA -> Centera then we need to use the build orphans tool built in with the CFA -->
Files that are stored on the EMC Centera, but do not have a relatedfile on the Celerra are called orphans. Orphans are created in two
ways:
◆ When a file is deleted on Celerra — Deleted files remain archived
on EMC Centera even though the file no longer exists on the EMC
Celerra.
◆ When a user modifies a file on the Celerra — When a file is
modified, CFA migrates the new version of the file while still
retaining the old version on the EMC Centera. These older
versions have no equivalent files on the Celerra and so are
technically orphans.
Note: CFA does not automatically delete orphans. Orphan deletion is a
manual process where the CFA administrator decides which, if any, orphans
to delete
In order to manage and delete orphans, you must first find orphans.
FileArchiver searches for orphans by both their inode Celerra handles
and their filenames and generates orphan lists.
Before deleting the files from the orphaned list, you may first want to
exclude certain files that you do not want deleted.
Once you have created the orphaned list and excluded any files that
you do not want deleted, you can run the process to delete all
orphans.
