Datestamps not restored

I’m doing my first restore in anger under Windows.

As you can see, timestamps are not preserved.

My restore command is::

restic restore -H Athena latest --path="C:\Users\Jnani\Documents" --target=c:\restore -v

I tried using \\?\C\ as mentioned in one issue:

restic restore -H Athena latest  --target "\\?\C:\restore-dates" -vv

But still no datestamps restored.

I then tried restoring on Linux:

All 3 listed times are just now.

Backups and restores were done with version 0.9.5

How do I restore all timestamps on both files and directories?

Oh, that’s odd. It works for me at least. Can you describe what you did? Did you take the backup on Windows and restored on Windows and Linux?

Can you check with restic cat snapshot <id> and restic cat blob <id> what the metadata stored in the repo says? Are there timestamps recorded?

Can you please try to reproduce the issue by saving a directory with a single text file, then share the repository with me? That’d be great so I can dig into the issue…

I cancelled the restore (I had a another method up my sleeve) when I found that timestamps were not being restored…

But then found that on a completed restore that timestamps are indeed set… but not the creation time.

Backup taken and restored on Windows.

Can you confirm that ctime is indeed expected to be restored?

After all files were restored, some datestamps were applied.

(16 Aug was when I did the restore)


Can somebody please confirm if the Created time is expected to be restored too?

Created time isn’t expected to be restored.

ctime is tricky, because on Linux it’s “change time” while on Windows it’s “created time”, and on Linux a user program cannot modify ctime.
AFAIK, Go doesn’t have a Windows-specific built-in function to change “created time”.

Here are my 2 cents :

I confirm that restic restore (completed) does indeed not write the original’s “created:” of the file. I think this behavior is expected since you are in reality creating a copy of the original file. I see the same behavior on a commercial Veeam Enterprise backup where if I restore a single file using “copy…” and not in place restore, the “Created:” date is today… This behavior is seen also under linux where restic restore creates a new copy of the file at the target (-t). Finding the “Created:” date is complicated (with inodes and debugfs) but consequent with the behavior you see in windows.

Now if I use an in place restore from Veeam (overwriting the original file), I see correct date for create date. But in reality, in 25+ year in IT, I never done that. ALWAYS do my restore elsewhere, there integrate back restored file by explorer copy. All these steps leads to “Created:” being recent.

To this regard, I think restic is doing just fine.
