I use the following Z-shell script. Rewriting to bash should be
trivial (probably no changes after the first line).
Note that this differs from yours in that it uses pg_dumpall
and dumps everything. You would want to change that...
-----------------------------------------------
#!/bin/zsh
# We prefer backing up to the SAN, but use the local
# disk as a fallback if the SAN isn't available.
backupdir=/u3/SolisDBbackups
if [ -d /mnt/san/SOLIS-files/db_backups ]; then
backupdir=/mnt/san/SOLIS-files/db_backups
fi
backupdate=$(date --iso-8601=minutes)
backupfile=${backupdir}/${backupdate}.dbtxt
echo "Backing up SOLIS databases to ${backupfile}.gz"
date
pg_dumpall -c | gzip >${backupfile}.gz
echo "Backup of SOLIS databases to ${backupfile}.gz done."
date
exit 0
--------------------------------------------
The crontab entry is:
-------------------------------------------
45 21 * * * /u3/SolisDBbackups/fullDump.zsh
-------------------------------------------
Hope this helps.
