freefilesync + linux + permissions

[+ffsuser+]

this is a question that bothers me for quite some time now.

i use freefilesync 9.9 64bit on linux to mirror my external hdds (ext4). the option 'copy file access permissions' is checked.

now when i double check the already synced drives with grsync (preserve owner, time, group, permissions), all new files and folders are mirrored once more in just a few seconds (incl disk writing activity).

checking back in ffs, all is still in sync after that run.

is grsync more accurate in terms of syncing permissions on linux than ffs is?

perhaps someone can point me to a more detailed explanation of freefilesync's ''copy file access permissions'' option for better understanding the above scenario.

You can check permissions from the command line via:

ls -l


On Linux FreeFileSync copies all file permissions using "chown" and "chmod".

hi zenju,

thank you for replying.

the file permissions are identical after syncing with freefilesync (ls -l), yet grsync always does a second run with the corresponding folders & files afterwards.

i am now on version 10.2, reading about changes with folder permissions got me excited, but the scenario still remains. grsync seems to introduce an extra approach, but looking at the options, i am not sure what this might be?

the following options are active - preserve time, owner, permissions, group.

the sync process with grsync is very quick, it does not seem to touch the contents - is this possible after all?
