Amoungst our troops there must be someone who knows how to write Cron-jobs.

I'd like to set up the UMSF server to automate backups of the forum DB and attachments folder, but it's just a bit beyond me. It's a LAMP setup using Cpanel 11.

Anyone who has 'the knowledge' to help me out - let me know!

No pay, but you can have an UMSF subdomain to put stuff on ( like Mike has for MMB anims ) as a UMSF perk biggrin.gif

Cheers

Doug

Hi there! smile.gif

If it's a simple file copy (or compress, copy file off box, delete local copy) that'd be pretty trivial to do. PHP's probably not the ideal language to write the script in though, a tiny shell script is probably the best way to do it.

As imipak says, if it's just about copying files it's quite simple. I use a bash script to copy, zip, encrypt and upload my docs to an external server. For a five times per month backup, a simple script could look like this:

#!/bin/bash
THEDAY=`date +%d`
THEDATE=`date +%m-%d`
if [ $THEDAY = 01 -o $THEDAY = 7 -o $THEDAY = 13 -o $THEDAY = 19 -o $THEDAY = 25 ] ;
then
zip -r ~/backups/backup-mydocs-$THEDATE.zip ~/folder/mydocs/
fi
echo 'Backup finished. Closing...'
sleep 2

That zips everything in the folder '~/folder/mydocs/'. The old backups get overwritten after a year.

You can edit the cron with "crontab -e". I do my backups at 20:16 because I know the computer is on at that time. The line would look like this:

16 20 * * * ~/backups/backup.sh >/dev/null 2>&1 # Backup,

---

Or you can use a script like this:

#!/bin/bash
THEDATE=`date +%m-%d`
zip -r ~/backups/backup-mydocs-$THEDATE.zip ~/folder/mydocs/
echo 'Backup finished. Closing...'
sleep 2

And a cron like this, for the same effect:

16 20 1 * * ~/backups/backup.sh >/dev/null 2>&1 # Backup,
16 20 7 * * ~/backups/backup.sh >/dev/null 2>&1 # Backup,
16 20 13 * * ~/backups/backup.sh >/dev/null 2>&1 # Backup,
16 20 19 * * ~/backups/backup.sh >/dev/null 2>&1 # Backup,
16 20 26 * * ~/backups/backup.sh >/dev/null 2>&1 # Backup,

PS. I decline the subdomain offer.
