cron.hourly jobs

i want to create a simple script to backup using rsync a folder on PC1 (suse 11) to PC2 (Windows XP) which can then be put into cron.hourly or cron.daily.

The target folder is mounted by a fstab entry:-

//	/home/badger_fruit/lan/backup	cifs	username=badger_fruit,password=mypassword,auto,uid=badger_fruit,gid=users,_netdev	0	0

By using the command …

rsync -avz /home/badger_fruit/data/photos/ /home/badger_fruit/lan/backup/

… it creates the files/folders/subfolders etc as expected (hoorah) BUT i get a message saying there was an error:-

bgrsvr-y:/etc/cron.hourly # rsync -avz /home/badger_fruit/data/photos/ /home/badger_fruit/lan/backup/

sending incremental file list
rsync: failed to set times on "/home/badger_fruit/lan/backup/.": Permission denied (13)
School Photos/

sent 4175 bytes  received 47 bytes  8444.00 bytes/sec
total size is 41067045  speedup is 9726.92
rsync error: some files could not be transferred (code 23) at main.c(1031) [sender=3.0.2]
bgrsvr-y:/etc/cron.hourly #   

I have checked that “everyone” has “full control” on the Windows share and that the folder is not in “read only” mode.

The username and password provided in the fstab are also correct, if i do a manual cp, it will work without any such error.

Any ideas from anyone please?

Try running it as your user (create your own crontab), rather than root,
that will ensure you keep ownership of the files.

an excellent idea, unfortunately, im a noob so don’t know how :frowning:
there are only two users on the “source” pc, root and “badger_fruit”, would i just change the ownership of the “/etc/cron.hourly/backup” file or move it somewhere else on the filesystem?

(ps, sorry, im such a noob lol!)

Stuff in cron.hourly is always executed as root.

If you want to run as some account, or even if you don’t, you should put jobs in /etc/cron.d, because that separates it from the system jobs and it’s easier to see that it should be retained across upgrades. The format is:

min hour day month weekday user command

e.g. a file /etc/cron.d/backupjob

2 2 * * * root /root/bin/dobackup

Every morning at 0202, run /root/bin/dobackup as root

To run as a different user, change the user field. But test that the user can indeed run the command. And remember that some environment variables will not be set, like $HOME, $DISPLAY, etc.

so to clarify

if i create a simple text file in /home/badger_fruit/data, chown it to use badger_fruit

called “backupfiles”, contents are:-

rsync -avz /home/badger_fruit/data/photos/ /home/badger_fruit/lan/backup/

chmod it to make it executable (eg chmod 555 backup)
then create a job in cron.d, called “runbackup”

the contents being:-

1 * * * * badger_fruit /home/badger_fruit/data/backupfiles

that would work?
(ie run at 01:00hrs every day as badger_fruit)

how would i know this had run? would it dump output to /var/log/messages, or some other place?

by the way, i ran it as badger_fruit and it “worked”, well, it gave the same error messages but didn’t complain about no permission to run this blah blah

Actually at 1 minute past every hour.

Output from the program, if any, gets mailed to the user specified. You can also divert it yourself.

1 * * * * badger_fruit /home/badger_fruit/data/backupfiles > /tmp/backup.log 2>&1

The 2>&1 merges stderr output to stdout.

ah har, that’s actually better for me, they are family photos and after my recent disaster i need to ensure i have a good mirror!

your code sample above, would that just dump the messages from the program output into a file and then append each time it’s run? because that is also fine, i can tail it if i want or open in nano/more/less/whatever.

Also remember to use the full path to rsync eg /usr/bin/rsync or use
the path statement at the begining.

I always use my own crontab for stuff like this, just run crontab -e to
create one. There are also some GUI tools for it as well, depends on
your desktop.

well i tried it, i set it up to run 15 minutes past the hour each hour and it did work but didn’t dump the output to a text file, it seemed to mail it to root; a few moments after it ran (and it did run, hoorah!) i was told “new mail in /var/mail/root”

opened it and saw the output.

is it possible to dump output into a file instead of mail?
edit- i also saw i still got the same permission error, despite running as badger_fruit :frowning:

Yes, the way I showed you. It should have been mailed to badger_fruit anyway so maybe you had not written out your changes or something else went wrong. If you want to append, change the > to >>.

Look at the man page for rsync, there are lots of options. Here is a
snippet I use;

FILENAME=/tmp/backup.`date +\%s`
/usr/bin/rsync -rlLtuzi --stats --progress --delete \
/home/malcolml/* /media/laptop_backup/opensuse/ \
/usr/bin/tr -d '\015' < $FILENAME | /usr/bin/mailx -s 'HOME Backup via
RSYNC to USB Disk' malcolml@localhost
# Delete backup file
