Midnight Backups

[syrocax]

I don't have much experience in PHP. But it would be neat to have a script for scheduled backups, I tought.
Script is OK. But how to run it automaticly if possible?

I am working on a rented space supporting PHP 4 operated by linux...

I couldn't come up with anything instead of configuring the script to run by a button and then setting the alarm-clock

Log into the server via telnet or ssh and type:

crontab -e

Move to a blank line, then type:

i

and:

05 * * * * /path/to/the/script

then:

ZZ

(this is all assuming you have vi set as your editor.)

The 05... tells cron to run the job 5 mins after midnight, each night.

Thank you. You have another happy coder now...

Actually, that line should be 5 0 * * * for the crontab. The one there runs 5 minutes after every hour. Also useful, but probably not exactly what you need at noon under load.

Do 'man 5 crontab' to get a listing of all the configuration settings for crontab. also, look at the /etc/crontab on a redhat or similar box to see what time root runs so you aren't competing too much for CPU/IO when you do your cron jobs.

Yep, sorry. Was thinking in another timeframe

Another good way to do backups is to put a script in /etc/cron.daily and it will be executed each day. This way, you just drop the script in the folder and it will be executed in turn.

i'm using the following crontab to do my daily reports run at midnight:
0 0 * * * php report.php >/dev/null

maybe it helps
