I'm working on an a migration of a file server from an on-prem storage subsystem , the storage subsystem uses compression and deduplication of files so for instance a volume of 19Tb consume only 4Tb . now that i want to migrate to Azure Files , i'm wondering if the share will have a size of 4Tb or 19Tb ?

Same question if i'm using NTFS compression on my local file servers , should i provision shares regarding the size of the local share or the size on disk on my local share (i.e the compressed value)

Hope my question was understandable :-)

    @Benmehidi, Hamza (TI-CSTI) Thanks for raising this question! Firstly, apologies for the delay in responding here and any inconvenience this issue may have caused.

    It will take the compressed data size while uploading to Azure Files Share(the size of data what you are uploading)! For more detailed information, you can refer to the below mentioned articles

    The limits for standard file shares apply to all three of the tiers available for standard file shares: transaction optimized, hot, and cool.

    2 Default on standard file shares is 5 TiB, see Enable and create large file shares for the details on how to increase the standard file shares scale up to 100 TiB.
