February 21, 20242 yr Community Expert I was wondering, why my backup server lost more and more files. Now I have noticed that the SMB setting "show DOT Files" on the main server has been set to "yes". My folder structure for videos contains a subfolder ".actors" for every movie. This was not seen anymore, therefor it was deleted on the backup server. But even worse! the folder and the files within have been deleted on the main server too!!! (no idea how this should have happened ?!?!?) So for everybody who updates: CHECK YOUR SMB SETTINGS after the update! Better not to set the array to autostart. (and of course, the value of this setting was "NO" for years and nobody here twiddled with it. It is even locked if the array is running (all the time)). So could somebody explain what happened and how to prevent such a desaster ? (naah diagnostics won't help it must have happend at the weekend already, now over 200.000 jpgs are gone...)

February 21, 20242 yr Community Expert Im confused. The setting is "hide dot files" and no is the default.

Suddently (after the update) it was set to "yes" I was confused too. Somehow it was set to "yes". And surely not by me. The only thing that happened last week was the update to 6.12.8 (and the needed reboot afterwards). MAYBE something before the update changed the ini file and it was later on activated by the reboot ? (again, not me!) Edited February 21, 20242 yr by MAM59

Regardless of that setting, Unraid would not be deleting any files on the main server as that setting just controls whether they are visible over the network. If they did get deleted on the main server it was done by something else.

February 21, 20242 yr Community Expert What did you use to update the backup? rsync has a switch which will delete files/directories from the destination if they are missing from the source. (I would avoid that switch like the plague in most backup situations. I have the rsync switches setup so that only new or changed files are copied to the destination and to never delete a file from it! Inadvertent file deletion from the source is often a 'cockpit error' situation that you would like to be recover from using the backup.)
February 23, 20242 yr After updating my test server, the 'Hide "dot" files:' parameter in settings > SMB settings remained set to "no". I could not find a 'Show "dot" files:' parameter however. Edited February 23, 20242 yr by Opawesome
