Will RAM Lower Load During Backups
Jun 18, 2007
On a Cpanel server, lightly loaded, but some fairly large sites (~3GB stored) loads get pretty high during CP backups (D/W/M to secondary drive, compression on). It looks like RAM is showing mostly used during this time (977,555 out of 1,026,348), and iowait is ~50, sometimes quite a bit higher at ~80 on the larger accounts. Not pegged at that amount, but fairly steady. This box only has 1GB RAM, so I'm thinking adding another Gig would alleviate this issue.
OS: CentOS 4.x
Hardware: Intel P4 3.6HT/1024MB/2x160GB

I'm hosting some domains on a whm setup. One of the domains has outgrown the shared hosting setup, so I'm moving it to it's own vps. I want to limit the downtime, and I understand I should lower the TTL on the domain.
The registrar is Network Solutions and the nameservers are pointing to the shared host (which is on a whm/cpanel setup). How can I lower the ttl on this domain? Do I have to move the domain to a more advanced DNS service to achieve this, or is this something I can do within whm?

I was checking my server information today on WHM panel and this is what I saw:
Processor #1 Vendor: GenuineIntel
Processor #1 Name: Intel(R) Core(TM)2 CPU 6700 @ 2.66GHz
Processor #1 speed: 1596.000 MHz
Processor #1 cache size: 4096 KB
Processor #2 Vendor: GenuineIntel
Processor #2 Name: Intel(R) Core(TM)2 CPU 6700 @ 2.66GHz
Processor #2 speed: 2660.000 MHz
Processor #2 cache size: 4096 KB
Why is the Processor #1 speed labeled as 1.6 ghz? Processor #2 speed never goes down no matter how high the load is. Could it be the reason that my server can't handle 4 websites with a cumulative total of 20k unique hits per day?

I'm gathering info for getting a new dedicated server, planning on using my own colocated hardware, but still looking at what's available in dedicated servers at the same time.
There are lot's of dedicated servers being offered at prices lower than 1U colocated rackspace. How's that possible, what am I missing?

I host my DNS with DNSmadeeasy.com , I noticed that I have daily more than 350.000 DNS requests for main domain, This domains got about 80.000 uniqes/day, so this is strange how can there be 350.000 DNS requests/day. Seems that I'll go over the quota because of this.
The TTL for all domains is set to 86400.
Is there a way to discover how its possible ? And also is there a way to do something to make this number lower (DNS requests)

I have a small issue that's probably easy to answer. If I upload a zip file to a Linux server, and run this command via SSH:
Code:
unzip -a name_of_zip.zip
Although it does unzip the directories as expected, it makes all file names and folders lowercase. This is a problem when trying to install software that relies on case sensitive names.
Does anyone know what command tells the server to retain the file names and not alter them?

I need to show a listing of all files in a directory that match a certain string, with *either* upper or lower case.
So if the contents of the directory are:
FILE1.txt
file1.txt
And then I do an "ls *file*"... I need both files to be in the results.
how can I do this? I couldn't find an "ignore case" switch when doing a "man ls".

I've been having trouble with my VPS for a while now. In the QoS alerts page in Virtuozzo it seems to be a problem with numtcpsock and tcprcvbuf, mainly numtcpsock.
Copy these into the browser:
i18.photobucket.com/albums/b106/gnatfish/qosnumtcpsock2.jpg
And when i run cat /proc/user_beancounters:
i18.photobucket.com/albums/b106/gnatfish/beancounters2.jpg
This line is particularly scary:
numtcpsock 164 164 166 166 7321
What do i need to do, to get the website running again? It's only one site on the vps a proxy. So i thought a vps would be able to handle one proxy.

Anyone know of some good server load testers ( commercial )?

I'm having the oddest issue. For some reason, some of the websites on my server load fine, and some take a really long time to load (2 minutes).
Now, the server load is fine, and the size of the sites aren't the issue either. I've restarted Apache and a couple more services, and still the same sites seem to load very slow.
What could be causing this since it's only effecting certain websites?

In WHM I set my backups to go to the / directory in a flder called backup. This filled up rather quick and that partiton is now full!
I was going to change the location to /home as i have over 400GB of space here but it says: Setting this to /home is a very bad idea.)

I've got a VPS with SLHost and have setup a remote backup account with RVPalace
The VPS is running WHM/Cpanel
I'm running a fairly busy forum and host a few friends sites on the server to. (CMS systems etc)
What's the best way to go about backing up the data to this remote host?
Would you say WHM's backup system is sufficient?
I don't feel comfortable with one backup every 24 hours, so i'm wondering if there's anyway to reduce that to every 6 hours?
Or would you guys recommend RSync instead?
I do have a question regarding RSync...something that worries me
If it's set to backup the sites every 6 hours and only backs up when something changes (Files/databases)
If, god forbid, a site gets hacked, but isn't noticed and Rsync kicks in and backs up the hacked site, there'd be no way to go back to a previous backup, would there?

I would like to know how to check load via ssh and check files causing load?
I want the ssh codes for 2 different set of control panels, one with cpanel+whm and other with kloxo+hypervm
and I would also know how to check the files causing the load, such as some files could have been interrupted while processing, so they could be causing load some times, so I want to stop such processes if any are running on the vps on my friends accounts

I have a dedicated server that only has around 3-4gb of data on it. I would like to do automated nightly backups for as cheap as possible. I don't want to pay to have my server managed just to be able to have automated backups, so what other solutions do I have? I know I can get really cheap storage from Amazon or Mosso, but is there a way to automate this?

I would like to know what is the difference in cpanel between a full backup and a daily or weekly backup, and how they work together. I was under the impression that a daily backup was a backup of all the files at the end of the day but apparently according to my host this is not so, and Im a bit confused as to what is the purpose of the daily and weekly backup.

FTP backups, doing RSYNC what is needed?
I have a linux box with pure-ftpd as FTP backup server. However, we want to explore/expand to RSYNC now.
Is there a package that allows RSYNC to be used for FTP users?
This is basically like what do FTP services like BQbackup use to allow RSYNC, etc.

if anyone knows about cheaper and reliable colocation services in East/ Central. I don’t need premium bandwidth (Internap, Level 3, etc). I need to colocate ½ rack to host my Backups, Bandwidth needed is 5 MB since I use Rsync at different hours, so I don’t need to push more than that.
I try to look for colocation services here in Colorado, but all companies quote me $50 to $70 for each server and $130 per MB.

Check this out... I was just diggin around in my Dreamhost panel and discovered something new that I've not even seen announced anywhere... Dreamhost is giving a BACKUPS user on each account, totally separately from the web user. You are allowed... well, I'll just copy / paste straight from the panel:
At DreamHost, you may only keep website-related content on your regular users. You do, however, get one user per account where anything legal may be stored; your Backups User.
This user cannot have any websites pointed to it, nor may you share files via it... it is only to be used as an off-site backup for your personal files.
As such, we keep no backups of files on this account. These are already supposed to be your backups... not your only copy!
(Of course, you should always keep your own copies of all data stored with us.. we make no guarantees!)
Every full DreamHost Hosting plan includes 50GB of backups space!
(Additional usage will be charged at the rate of 10 cents / GB a month: the best backup deal on the net!)
Pretty interesting... they didn't HAVE to do that, it's just another one of those things that they give in order to be even MORE awesome, evidently.
