Meta data not retained using DataSync.
A customer is migrating the data from on-prem to AWS S3. Customer would like to retain meta data information i.e. file created date, modified date after migrating to the S3.
As the data size is almost 25TB, and have very good bandwidth, planing to use data sync.
As per data sync documentation given below, I thought customer can retain the meta data information which they used for Audit purpose.
When copying between an NFS server and Amazon S3 – In this case, the following metadata is stored as Amazon S3 user metadata:
File and folder modification timestamps
After migration, I see the date and time migrated but not the original created date.
How to retain the actual file dates after migrating to the S3 bucket?

When Copy timestamps is selected, DataSync will preserve both the source file's atime (access time) and mtime (modification time) properties. Neither the NFS protocol, nor the POSIX API set, provide any facility to obtain, nor even a requirement to preserve, a file's creation time. So it is not possible for DataSync to preserve this as there doesn't exist a means to acquire it.
