I have my WHM/cPanel installation configured with daily and weekly backups. I checked at what time of the day the server load was at the minimum and configured the cPanel backup cron to run then.
The problem now is: Backing up a few hundred accounts results in a high server load. My server configuration:
Dual Processor Quad Core Xeon 5335 2.0GHz with 4GB RAM and 2 x 250GB SATA HDD hosted at SoftLayer.
The accounts are located on the first HDD and the backup archives are placed on the second HDD.
What can I do about this? I'd like to take daily backups of all accounts but not if my server load increases up to 10... That kind of renders the cPanel backup feature useless if it doesn't even work on a powerful server like this one...
Would it help if I use an application such as Auto Nice Daemon to give the backup process a lower priority? But then again that won't work on the MySQL dumps? And I think it's not a CPU problem but an I/O wait problem? Other processes have to wait for disk access because the disk-intensive backup process is running?
to decrease the load in server when daily backup start ,, the load in server before backup start from 0.80 to 1.20 after daily backup started i see very high load from 16.00 to 32 and 40
any solve for decrease load when backup start from 3 to 7 alot
I have seen resellerzoom provides daily full backup to their customer. How should i configure my WHM so that it create daily backup and delete old backup.
customer of HostV's VPS hosting, and for the past 3 days, at almost exactly 01:20 GMT, CPU load jumps from an average of about 0.10 to 2.5+, stays there for over an hour, then drops back down.
During this time, there are NO processes on my virtual server using any significant amount of CPU time, memory, or IO. No cron jobs are running on my server, etc.
Note the output from 'uptime' below (I was monitoring it waiting for the problem to occur, which it did at exactly the time I expected):
00:32:05 up 22:01, 2 users, load average: 0.09, 0.11, 0.08 00:32:07 up 22:01, 2 users, load average: 0.08, 0.11, 0.08 01:09:49 up 22:39, 2 users, load average: 0.06, 0.03, 0.00 01:10:03 up 22:39, 2 users, load average: 0.05, 0.03, 0.00 01:19:26 up 22:48, 2 users, load average: 0.46, 0.16, 0.04 01:20:42 up 22:50, 2 users, load average: 1.53, 0.55, 0.18 01:21:39 up 22:51, 2 users, load average: 1.40, 0.67, 0.24 01:46:04 up 23:15, 2 users, load average: 3.06, 2.02, 1.52
Also note output from 'top', taken when load average was at 3.06 shown on the last line above:
My cpu usage is very low (0.1%) but wait time is at 9.0%, and I've seen this go as high as 70% during these times.
So, basically, there is a problem that exists on the host node somewhere that is causing my site to become effectively unresponsive (page load 20 seconds+ - measured), and it happens every single day at the same time.
So, why am I posting it here instead of logging a trouble ticket? I have logged a trouble ticket, but when I encountered the problem yesterday, despite logging it as "CRITICAL", I had to wait nearly 5 hours for a response, which effectively said not much beyond "we noticed the problem and fixed it and we're monitoring it". So I don't have a lot of faith that today's response will be any better.
I moved to HostV because of similar problems I was encountering with shared hosting, and was assured before signing up that the kind of problem I'm seeing doesn't happen. So now I'm outlaying more than 10 times the cost for almost exactly the same problems and a similarly unhelpful response to it.
By publicly posting the problem, I would hope that someone at HostV will ensure the problem is addressed PROPERLY, rather than bandaided again, and that hopefully we will all be able to see just how good HostV's support CAN be (as evidenced in another similar post).
I await HostV/Cirtex's response.
As shown in the uptime information about, server uptime is 23:15, because I rebooted the virtual server yesterday to see if that helped. It didn't. In fact, it took over 20 minutes for the server to come back up, which is why I'm not going to do it again.
i just wana know is it safe to do remote daily backup for about 70,000 files?
file sizes is about 200kb and every day i have about 1000 new file, so rsync first should check old files becouse i am deleting about 30-50 of them daily and them backup new 1000 files , so how much it will take every time to compare that 70,000 files?
i have 2 option now:
1-using second hdd and raid 1 2-using rsync and backuping to my second server , so i can save about $70 each month.
I'm new to Parallels Panel. I use version 11.0.9. I want to backup mysql database daily. First of all, what is the best way for daily database backup in plesk. I'm trying to do this in Scheduled Tasks and I use mysqldump command although I'm not sure.
I chose the time and day first and then I switched on the task. I typed the following command to Command line.
This created only a blank file. When I use this without gzip, nothing changes.
1- Is mysqldump right command for database backup? 2- Should I define full path for mysqldump, gzip and database? If so, how can I find out the full path of mysqldump, gzip and my database? Because I can't see their locations in panel. 3- I can't see any error message. There is not any log file in httpdocs folder. Where does the log file exist? 4- It is weird but should the username be "database user" or should I write "root" ?
I have a dedicated server specs: AMD 3500+ 64 Bit CPU, 1 GB Ram, 160 GB Sata Drive. For 1 month, CPU load average reaches 40-50 value. This happens about 5-6 times in a day. When I stop httpd service for 30 seconds everything goes normal. I think this is not a DoS attack because it comes systematic, I dont believe no one makes this regularly except bots.
Maybe its a system service or a cronjob but it stops when I turn off httpd service? How can I be sure about what's making this regularly load?
I also did set up a script which mail me when load average of system goes crazy and restart httpd service. But instant restart is not working to stop load increase.
A couple weeks ago, I encountered a big server crash on my VPS that caused me a lot of downtime. I'm currently trying to figure out a solution to keep a current "clone" of all of my server accounts on a second server. That way, if I ever encounter another crash, I'll be able to simply change DNS information to have all accounts "live" using the backup server.
I appreciate any input, advice, suggestions, criticism, etc. Here's what I have in mind...
1. I currently have all of my websites hosted on Server #1. (We'll call it that for the sake of avoiding confusion.)
2. I have an automatic nightly backup setup via cPanel / WHM that backs up all accounts from Server #1 to Server #2 via FTP. (Server #2 is in a totally different data center, with a different provider.)
3. The nightly backup packages all of the accounts as "cPanel Full Backups." So, they're compressed, and as such, they don't work as "live, functioning websites" on Server #2.
The only way to make them "live and functional" on Server #2 would be to use cPanel to "restore" the backups.
4. So, what I'd like to do is setup a CRON job that would automatically "Restore" the backups each morning on Server #2. That way, Server #2 would always have a functional version of all my accounts, that is less than a day old. Then, if Server #1 ever crashed, I'd just have to change DNS information to point to Server #2, and all of the websites would be live again, without having to physically restore all of the backups using cPanel.
I don't know a ton about CRON. However, as I understand it, CRON couldn't actually make cPanel restore the backups. However, I'm assuming that when you use cPanel's "Restore" function, it just goes through a series of processes. So, it seems logical to me that, if you knew what those processes were, you could write a CRON job to automate the process every morning.
Did that make sense?
If so, is it possible?
Do you guys have any input, criticism, etc?
If it's doable, can you make any suggestions that would help me make this happen?
Finally, if you think you have the expertise to make this happen, I'd be interested in chatting with you via Private Message. I'd be willing to pay to have this done.(Note to Moderators: I'm not sure if my last comment is allowed or not ... if not, please feel free to remove it. I'm far more interested in the discussion of this process than trying to solicit help in making it happen.)

we have a dual xeon 2.8G +2G ram CPANEL server normally load is well under2 and stable
we also use Incremental Backup and choose Per Account Only for MySQL backup
This server mainly hosts a big site, whose SQL is 1.2G big
Everytime server is running backup, load burst to 7 and accessing to website hanged. We are thinking to change SQL backup method to Entire MySQL Directory , but was told while it is processing SQL server will be stopped ?? wil Entire MySQL Directory reduce server load while processing SQL backup?
