[Hcoop-discuss] rsnapshot problems

[Justin S. Leitgeb]

According to the log files, it is probably dying out on the system command:

/bin/cp -al /home/backup/rsnapshot/daily.0/ /home/backup/rsnapshot/daily.1/

Can someone with root do an strace on this command, when run manually, 
and dump it to /tmp for further diagnostics?  It would probably look 
something like this (except having the destination go to 
/home/backup/testing so that we don't mess up rsnapshot's directory).

strace /bin/cp -al /home/backup/rsnapshot/daily.0/ /home/backup/testing 
2>&1 > /tmp/strace.out
