backup bogs down server... why?

[dandanfireman]

Why does the load go up? Keep in mind that the files are compressed. So everytime the server is backed up, most of the files on the server are copied and then compressed. What drive/partition are you backing up to?

its a dual p3 1.13ghz with 1gb ram

im backing up to /backup/

my backup script runs on thursday... how can i set it to run on a sunday at 2am?

my cron shows:

6 3 * * * /scripts/upcp

is this okay?

Why does the cpanel backup script slow down the server so much?

sometimes server loads reaches 8.0 when cpbackup is running.. causing dns or mail server to go down.. Does anyone know a better backup solution?

I would also like to know how I can set my backups and awstats to run at night. These things cause my server's load to go very high. I have some sites getting 4000 hits per day... so their logs become HUGE!

what are your system specs?

[(SH)Saeed]

Run it at night when the the traffic is at lowest.

I have a site that gets 200k hits a day and logs are huge. Backup runs every night. I have never seen over 3.0 on loads. 300 users only.

Your upcp script is running at 3:06am every morning which should be fine. I do my backups at 5am because that's when there is the least activity on my server.

Why does it run on a Thursday???? How do I change it to a Sunday????

[PWSowner]

Right now it is set to run every day, not just Thursday, at 3:06am. To change it you need to edit this file.
/var/spool/cron/root
To only have updates run on Sundays at 2am, the upcp line in that file needs to be changed to
0 2 * * 0 /scripts/upcp

THANKS for that.. btw, atm my MRTG script is running via cron,however i deleted MRTG but the CRON cannot find it. I keep getting lots of error messages such as:

From: Cron Daemon

/bin/bash: /usr/bin/mrtg: No such file or directory

---

Does anyone know where this CRON file is located? I really want to remove this because I am getting an email sent to me every 5minutes!

[PWSowner]

You deleted the script but cron is still trying to run it and telling you that it can't find it. You need to remove it from the cron list.
That one is in the crontab file at
/etc/crontab

There is a line like
0-59/5 * * * * root /usr/bin/mrtg /etc/mrtg/mrtg.cfg
Just remove it.

squirrel you are my HERO!!
Thanks

Your welcome.
It was only a couple months ago that I figured this stuff out. I wanted to understand my server so I downloaded the whole thing to my hard drive so I could investigate safely. A lot can be learned by looking through the files.

I have the exact same problem... I've dug around as much as possible and it appears to happen when log files larger than the cache memory available are copied during the backup process.

Same thing happens when daily backups are rotated to weekly backups - the backups larger than the servers ram will cause the load average to scream out of control and the servers services will become unresponsive to new connections.
