Deduplication file check
Hello, I wanted to ask you if you know of a way to check the health of the files that were deduplicated by the Data Domain DD2500 so we know that they are not corrupted.
Thank you.
Regards,
Pablo

Sure - you can obtain a small amount of info about any file written to DD from the CLI.
Use 'filesys show file-info ' and 'filesys show compression ' :
sysadmin@dd860-bbc-mgmt# filesys show file-info /data/col1/cifs_sql/ABCSQL3/ABCSQL3_Parking_Full_201606160100.safe
Name /data/col1/cifs_sql/ABCSQL3/ABCSQL3_Parking_Full_201606160100.safe
Storage Unit Active
Status Ready
Diskgroups dg1,dg2,dg3,dg4,dg5
sysadmin@dd860-bbc-mgmt# filesys show compression /data/col1/cifs_sql/ABCSQL3/ABCSQL3_Parking_Full_201606160100.safe
Total files: 1; bytes/storage_used: 11.1
Original Bytes: 160,248,052
Globally Compressed: 14,191,772
Locally Compressed: 14,312,944
Meta-data: 60,344
Let us know if that helps!

The Data Domain handles file integrity at the block level as part of the process to write files and perform garbage collection. There is no user-facing command to check file integrity. You can, however, view details on a file from the CLI.
Let us know if that helps!
