Re: [rdiff-backup-users] cron job opens and closes ssh without copying.

Hi all,

After trying Roland's suggestion to wrap the script I realized that it
works when wrapped.

11 12 * * 1,2,3,4,5 /copies/commands/xen1-bcn.home.sync

more /copies/commands/xen1-bcn.home.sync
#!/bin/sh
/usr/bin/rdiff-backup -v 1 address@hidden::/home/pas /copies/xen1-bcn/pas

But if I call rdiff-backup directly from crontab, I have the reported
problem. Strange things do happen.
Perhaps it is my old, not updated, unmaintained rh7.3 that's causing
this anomaly.

I see if it works again tonight.

Thanks
Chris.

Hi,

(or put backup.sh >/tmp/backup.log in crontab)
/tmp/backup.log empty :(

Mirror is about 12 minutes into the future in respect to primary.
That doesn't matter, does it?
