file modify date/time is not preserved

[udo.sander]

Dear community,

I want to use FFS to backup files from my Linux Mint 21 computer to a WebDAV cloud storage in sync mode mirroring. and compare mode date+size.

For this, i have mounted the WebDAV drive via following entry in /etc/fstab:

https://<an-openxchange-server>/servlet/webdav.infostore /mnt/OXDrive davfs noauto,user,uid=udo,gid=udo 0 0

The access via this mount works in principle, and FFS is creating the mirrored files on it.

The problem is:
The creation/modification date/time of the source files is not preserved, they all get the current date/time on the WebDAV share.

This makes the tool unusable, because on the next sync, it assumes that all files have changed and copies them again.

How can I configure FFS so that it creates the files with their original modification date/time?

Thanks for your help!

Are you sure it is not an issue on the WebDAV end?

If you some other method to copy files to the WebDAV, are the date/time stamps preserved?

cp -p (or whatever)

Yes, you are right! Thanks for that hint.

When I copy a file via Linux file manager to the WebDAV drive, then the same problem occurs, date/time is set to the current date/time.

If anybody knows how to mount a WebDAV drive in Linux so that it preserves the datetime, I would be glad if they could post that here.

Thanks!
