I have a SOHO Synology NAS that runs a Linux based system. Due to some system limitations I need to have a shared folder called backup to hold all backup data from my SOHO computers (that means Linux, OS X and Windows computers). I'd like to configure permissions inside backup so that each and every logged-in user would only see and interact with their own folders and data. For example:Ana is logged-in and backup her MBP using Time Machine on /backup/Ana's MBP.sparsebundle/Bob is also logged-in and backup his Windows using File History on /backup/Bob/PC01/Charlie is logged-in too and backup his Windows using File History on /backup/Charlie/PC05/So, everyone is online at the same time backing up their data on backup but neither of them can see each others folders/files. I'd like to be able to enter inside backup folder, let's say as Bob, and only see the /Bob folder inside and nothing else.Is it possible, how can I achieve this?
How to configure permissions in this case?
permissions;users
I believe I got it working, it may just work on Synology DSM systems that run Linux based, so YMMV. First we have the Shared Folder backup (you can name it whatever you want). After you create it you should edit its configurations like that:Uncheck 'Hide this shared folder in My Network Places'Check 'Hide sub-folders and files from users without permissions'Inside Permissions tab set:Owner: Allow Full Controladmin role: Allow R/Wuser role: Allow Create folers/Append dataEveryone special role: Allow Traverse folders/Execute files and List folders/Read dataThis way each user would be able to point their backup softwares to /backup and store their data without seeing and interacting with other's data. For testing, I logged-in as 'Bob' and saw my File History folder but couldn't see 'Charlie' Time Machine folder.I then proceed to disable 'Hide sub-folders and files from users without permissions', now I could see Charlie's folder but couldn't interact with it as I got permission error, just how I wanted, after that I enabled hide again and only saw my folder/files.It's working, I just don't know if it's a good practice, but I believe there isn't much to do as the system has some limitations. If someone have a better workaround, feel free to answer!
