Here is my idiom; checking for success is vital.
See openssh documentation for details on key-based shell access. Test for
transparent access, if using gpg, test for undisturbed encryption with --batch.
You can pipe the dump (or tar) to gpg instead of gzip. File size will be
reduced. The dd command can also hit a tape, though this isn't always practical
with nightly cron stuff.
OK=`/sbin/dump -0 -f - / | gzip | /usr/bin/ssh x.x.x.x dd of=/path/ok.gz 2>/dev/null;echo $?`
if [ $OK != 0 ]
echo "`date` `hostname` backup failed $OK" | mail you
echo "`date` `hostname` backup $OK" | mail -s "`hostname` backup $OK" you
>> Is there any documentation on how to do that?
