Hi,

Without too much 'techno-babble', could someone explain why I would want to stop the vss. Is it because active vss during defrag might mess up restore points?

Thanks.

I presume it's to prevent restore point expansion during defrag.

moving the files around with VSS enabled will trigger the creation/expansion of a restore point, which will cause more fragmentation.

In that case, why would the default setting be set as not to stop the vss?

Thanks.

That option was likely introduced only cos a few users with low disk free space complained of losing restore points. If you have plenty of free space I suggest you leave the option ☐unticked, cos the VSS expansion provides a safety net in the rare event a defrag messes a file. Better safe than sorry.

Also some people don't like their services disabled without asking!

Some of us would consider it disrespectful - and worse.

Sometimes Windows cannot even do one job at a time - I do not trust it to do two or more jobs at a time.

Others may be more adventurous. They may even defrag whilst making a partition image backup.
Creating a backup will not end well if defraggler stops VSS.

In theory VSS gives a consistent image capture and the backup file will not see defraggler's work in progress,
but as I said before - I do not trust Windows to do two or more jobs at a time. :unsure:
