Rsync to Network Share works from cmd but fails from Scheduled Task
Greetings, I have written a C program that runs on Windows servers and does overhead and reporting for backup administration. The program calls rsync for the actual data copy function. It copies data from a remote system to a local drive and that works fine. However, I have recently made changes to copy the data to a mapped drive on a NAS device instead of the local drive. The changes work fine when run from a command line, but fail when run from a scheduled task or cron job: rsync: mkdir "/cygdrive/q/restores" failed: No such file or directory (2) rsync error: error in file IO (code 11) at main.c(675) [Receiver=3.1.2] Note: The folder already exists and permissions are open for Administrator. Command line that works is bash command to call the C program under Administrator login. Scheduled task built as Administrator with or without highest privileges fails. Tried Cron entry built under Administrator and it fails. Here is the Rsync command (abbreviated) called by the C program: rsync -rltgoD --chmod=Du+w,u+r,u+x -e "ssh -p 33222 -i \"/cygdrive/c/Users/administrator/.ssh/id_rsa\"" --stats --files-from=/... -vv --exclude-from=/ @remote:/ /cygdrive/q/restores Note: q is the mapped drive to the NAS share. So, what can be done to track this down? Why would running as a scheduled task or cron job fail when command line works? I am willing to do any kind of tracing if someone can provide directions on how to do that. Thanks in advance, Leon -- Please use reply-all for most replies to avoid omitting the mailing list.

It may not be possible.
Based on experience with FreeBSD, from which much of OSX is derived,
I suspect you may be running into issues with "file flags"; check the
OSX documentation for the chflags system call. In FreeBSD, I've seen
that same error message when rsync attempts an operation that would
violate chflags restrictions.

"full disk access" likely refers to the ability to read the disk
directly, bypassing the filesystem. It's used by maintenance
programs like fsck and fsdb, and by some full-disk backup programs,
but it won't help rsync.

Re: osx permission issue
what makes you believe that ssh is accessing the files ?
ok, rsync on remote mac is being spawned by sshd, so i gave full disk
access to the sshd binary , too (as it may inherit restrictions to sub
processes) and restarted ssh service ,
but unfortunately it makes no difference.
did you mean that or something different ?

Hi Roland.
You might have to give ssh full disk access on the remote Mac, as that
is what is accessing the files according to the Mac.
