... that interferes with FFS use of VSS. Does anyone have a solution or will there be an update to solve this? I am on version 14.9 - 64 bit. Obvious workaround is to shut down programs like Outlook that have locked files, so that the backup can be done without VSS. But am hoping for a better solution.

... to the above "user access" bullets, there are two extra attention points:
• An application a user uses to access a file, may lock that file (e.g. Outlook and *.pst files).
FFS can only copy locked files when using Volume Shadow Copy
• After a file is marked to be copied source=>target during the ...

Hi, thanks for your reply.
I've closed Outlook, right clicked on the FFS link in the start menu and opened as administrator, unticked and reticked "copy locked files", resyncronised my two locations, resaved the batch file to sync my two locations, run the batch file through RTS and still get the same ...

The Outlook data file is locked by a process
To copy locked files in FFS, the setting "Copy locked files" needs to be selected
To copy locked files, FFS uses the VSS (restore point) service in Windows
To use VSS, you have to run FFS as administrator

You can close/kill Outlook before running the sync ...

I've done nothing other than go through a Win11 update and on restarting my outlook backup batch file I obtained the attached message. No idea what to do, any help would be appreciated. Many thanks Bill

The Outlook data file is basically always being touched, even if it ends up being unchanged, ask Microsoft to figure out why. If you are using RTS to monitor a location containing it, it will trigger RTS to fire off the command line. You didn't mention RTS though, but I have to assume you are using it ...

Why does Windows report a file change for outlook .pst-files without any outlook activity? FreeFileSync is running a lot without changes in the .pst-files.
FreeFileSync creates a Volume Shadow Copy every now and than. Why?

https://freefilesync.org/manual.php?topic=volume-shadow-copy

Can FFS do "shadow" copies, e.g. Outlook.pst when Outlook app is not closed?
Maybe I am using the wrong word "shadow", what I meancis if a data file is opened in another program or by some process, can FFS still make a valid copy of it?

... ports.
- The source HD file system is NTFS and the sink HD file system is exFAT.

- Prior to the mirror operation, the sink ...

... folder down.
• Gets the name of their immediate parent folder ($parentName).
• Builds a destination path F:\TEST\<parentName>\output.

... on both sides it doesnt know which it should keep, but for me id always want to keep the newest. In theory it wont happen with normal saved files

Before I had made a backup sync of my outlook files and used the filter setting to *.ost and *.pst, this setting was still there when I created the new 2WaySync, so when my folders in that ...

... GREAT idea!

Wish I had thought about it. It sounds logical and should work. It's better to have the mail server use a server-side forwarding rule (I do this in Gmail) so it's always active. Not depending on Outlook client for example to forward the email only after the app is run on the client.

... or in your mail program.
E.g. have FFS send the E-mail to said test1@mail.com account
and at your test1@mail.com provider,
or in your mail program (e.g. Outlook) that receives test1@mail.com mail,
define a forwarding rule based on Sender or on Topic to forward
those mails to test2@mail.com.

I've copied below the log-file. It looks as though outlook being open is creating the error, but I had no issue with outlook being open in win10 ?

I've been using FreeFileSync for a number of years in Win10 to sync my outlook pst file from it's user drive to a backup drive with a batch file running every 10 minutes. Never had any problems.

... synced to the adobe cloud.

Maybe I'm paranoid but I don't trust the cloud.

My idea is this: have FFS copy some important files (such as my outlook pst) to that folder. But have everything copied to that folder encrypted, so when they are copied to the cloud they are secure.

I want to be able to skip files that are in locked and copy them only when the aren't locked.

One example is the "Outlook Data File.pst" file. When i have Outlook running this file is locked and FFS can't copy the file. If Outlook isn't running the file can be copied ...

Disabling Fail-safe file copy didn't solve the issue and I still got an error message:

Cannot copy file
"\\192.168.10.199\Workroom\Backup\Outlook\TomerDor.pst" to
"C:\TomerDor\Outlook\TomerDor.pst".
ERROR_UNEXP_NET_ERR: An unexpected network error occurred. [CopyFileEx]

This is not the issue.
This is indeed an Outlook file, but it is not opened during the sync process (Outlook cannot even run on this device which is only a network disk and not a Windows machine).

Assuming Outlook uses the TomerDor.pst file, if you opened Outlook while FFS was performing the sync, Outlook will lock the *.pst file, and FFS will not be able to copy the file (any more).

... get the following error message after around 80% of the file were copied, and the sync fails:

Cannot copy file

You only need donation for the natively supported emails, not to run a post-sync command

Thanks for the responses. Do you need the donation version?

If you can write a script to tell outlook to do that, sure!
Just put the terminal-command to execute the script in the "run a command on completion" field.

Writing a script seems to be easy: https://www.google.com/search?q=powershell+send+email+outlook
Other kinds of scripts should also work somehow

Can MS Outlook be used for sending the sync notification?

Same problem... The last version I installed (11.11) doesn't sync Outlook Desktop files.

...so I restored my D drive manually, by copying the files in Explorer. Everything was fine, the D drive and the backup matched. And then I ran FFS, knowing the two drives were identical apart from my Outlook files, and now I have 8.7GB inaccessible space on my D drive again. What gives???

They probably generate different traffic type.

What's the name of your email client?

If it is Microsoft Outlook, for example, the mails are contained in a few files that can be very big, and this generally can generate the wi-fi issue that you are experiencing.

Open Outlook first? How long does it take to back up your PST? Use a scheduled task to sync?

... and I know what happens.

The problem comes when the scheduled task that I have assigned to run FreeFileSync runs before the user has opened Outlook.

What happens then is that FreeFileSync does not create a VSS instance and therefore, when the user opens Outlook while FreeFileSync, it starts ...

*.ost-files are normally locked while Outlook is running/open.
Try closing Outlook and then sync again.
Or try using volume-shadow-copy.
