Restored EFS, but the file size is significantly smaller than the original
The Problem
After restoring EFS, the restored file system only shows a few KiB in size, while the original was several GB.
The job is completed, but has the restoration not been successful?
How to solve it?
As stated in the documentation below, after a file system restoration, files are synchronized asynchronously.
Therefore, it may take time for the measured size to appear on the console screen even after the restoration is completed.
-----Excerpt-----
When an Amazon EFS restoration is completed, files are loaded asynchronously. If you are monitoring Amazon EFS or Amazon CloudWatch metrics, the metrics may not show the actual size of the restored file system.
-----Excerpt-----
When the restore job status becomes COMPLETED, the restoration is complete and all files have been restored to EFS. Please wait for the size indication to resolve itself over time.
