One of the challenges with S3-style object storage (like Wasabi) is that it does not naturally preserve the file date attribute. For example, if a file on your local computer has a date of 1/1/2025, you copy it to Wasabi object storage on 1/2/2025, and then pull it back to your local computer at a later date, the file will no longer have the 1/1/2025 date.
There are storage clients that work around this issue by encoding date stamps as part of an encapsulation mechanism. This approach ensures that the date and related file information are fully preserved. Most S3-capable backup programs take this approach. But, if you are using simple S3 client file utilities (including the Wasabi Management Console), you will notice that the date information is not preserved.
