Greetings,
Here's a problem we're facing:
Our rsnapshot server uses rsync over ssh to backup several Windows
servers, which are behind Linux firewalls.
What we have been doing is mounting the Windows NTFS/FAT32 filesystems
into the Linux firewalls, which are then available to the rsnapshot
server using rsync over ssh.
This has been working great for quite a few time now, but sometimes one
of the Windows servers is down for some reason, so it's filesystems are
not mounted on the Linux firewall, and so the rsnapshot silently runs
copying *nothing* from the folder where used to be 30 GBytes.
Can you think of a quick way to "cancel" rsnapshot if the remote folder
is empty, or if the remote filesystems are not mounted, or something
like that ?
Before running rsnapshot, test that the remote dir is accessible, possibly by
running rsync without a target defined, so that it returns a file listing.
eg in a shell script
testit=`rsync root < at > 1.2.3.4:/my/path/ 2>&1 | grep 'failed:' | wc -l`
if [ $testit = 1 ]; then
exit
fi
the above line will return 1 if the dir cannot be reached (or does not exist)
otherwise it returns 0.
Regards,
--
