Disk Usage in cPanel
The cPanel Disk Usage Viewer provides an overview of the disk space that your account is using. It shows disk usage totals for your account’s directories and all of its databases rather than for individual files or databases.
To view the disk usage, please login to your cPanel account and click on Disk Space Usage icon in Files section:
The bars in the graph represent disk usage figures relative to the largest directory, not according to a fixed scale:
You can use the File Manager to see disk usage data for individual files, and the MySQL main page to see data usage for individual databases.
Some other import folders to keep in mind are:
/tmp for stat reports (AWStats, Webalizer)
/logs for raw web server logs
/mail for email data for all domains in this account
/etc for email login/passwords
Due to the nature of how files are stored electronically, most files occupy slightly more disk space than their actual size. For example, a 300 byte file may occupy 4 kB of actual disk space. This may cause discrepancies between the data you see in the File Manager versus the information you find in Disk Usage page.
Moreover, the disk space usage in the table above indicates how much space the directories’ contents use, not how much space the directory itself uses. Directories themselves usually use a negligible amount of disk space unless they contain a large number of files or subdirectories.
We hope this is helpful information. If you need any assistance, please contact support.
File Manager in cPanel
File manager allows you to manage and edit the files right inside the cPanel interface. You do not need to download/upload the files or require any special software on your computer to edit them. Although this method can be used to create entire website however it is meant for quick fixes or edits on the fly. Normally you would want to keep a local copy of files that you maintain and edit in a developer environment such as Adobe Dreamweaver.
You can access the File Manager under Files section as shown in the screen shot below:
When you click the icon, a small popup window will show to select a folder to open in File Manager. You can choose Home Directory which contains all other files and folders, or you can go directly to web root (i.e. public_html) folder which contains your main website files. Or if you have multiple websites hosted, you can go to any particular document root.
You also have the option to Show Hidden Files (files that start with dot) and you can skip this popup in future if you want to open a particular folder every time you go into File Manager.
Once you have made the selection, a new tab or window will open with the File Manager.
You will have the folders in a tree structure on the left and files in the selected folder in the right pane. You can do many functions such as Create New File, Copy, Move, Upload, Download, Delete, Rename, Edit, Change Permissions, and View files. For example to rename the file, highlight it and click Rename icon on top menu and you’ll get a popup window to enter new name:
Similarly other functions can be performed. While editing you have the option to edit as text or HTML Editor:
You can also do code highlighting when editing code files using Code Editor:
We hope the File Manager can be a handy tool. If you need any assistance, please contact support or you can post your comment/question on this blog.
Horde Address Book Showing NULL
Horde is a popular webmail software and comes installed with cPanel. We had a situation where accounts were moved across servers using WHM on a cPanel server. After the upgrade customers reported that in their horde address book entries, they see NULL with the names of their contacts.
We have removed the names for privacy from the screen shot above. We investigated the issue and found that the table turba_objects in horde database is holding literal NULL text instead of NULL datatype. We had to run multiple SQL queries like the following to get all the records updated:
|
1 |
UPDATE `turba_objects` set object_lastname=NULL WHERE object_lastname='NULL' |
Once all the columns were updated, there were no more NULL text displaying in customer’s contacts. It looks like when cPanel/WHM did the data transfer across servers, it somehow enclosed the NULL in quotes making them literal text.
Taking Backups of Web Hosting Account in cPanel
Although we backup entire hosting server every day and keep consecutive backups for several days and weeks, we strongly recommend that every client should have their own backups. The backups we take are for emergency purpose i.e. disaster recovery in case of hardware failure such as multiple disk failures.
The question may arise, how do you take a backup of your entire website? And which files to backup? cPanel makes it easy. Taking Backups of Web Hosting Account in cPanel is straight forward process.
cPanel Backups allow you to download (to your computer) a zipped copy of either your entire site (including your home directory, databases, email forwarders configuration, and email filters configuration) or one of the previously mentioned parts of your site.
As highlighted in the screen shot below with red square, you can find the Backups icon and link under Files section in cPanel. Click that to access Backups screen.
The next screen has a video tutorial on how to generate a full backup. We explain here as well.
Full Backup
A full backup includes all of the files in your home directory, your MySQL databases, and your email forwarders and filters. You can back up your account to preserve your data, or to move your account to another cPanel server.
Click on “Download or Generate a Full Website Backup” button to proceed:
This full backup can only be used by server administrator (with root privileges) to restore entire account settings and data (including website files, mysql databases, emails). It cannot be used on the cPanel interface by you to restore an account. It is useful for safe keeping.
Generate a Full Backup
You can generate a full backup and store it in
a) Home Directory i.e. you can use ftp or file manager to download the backup when created from /home/username/ folder (where username is your cPanel username)
b) Or you can upload the backup to a remote FTP server or SCP.
You also have the option to enter your email address where notification will be sent by cPanel once backup is completed.
If you choose to upload the backup on a remote FTP server, you will need to provide the login details:
Click Generate Backup to proceed and wait for email confirmation. In case email does not arrive for a long time, you can visit the Backups screen again to see the progress:
And when it is complete, it will show up with a link to download. Simply click on the link of the file to download the backup on your computer.
Partial Backups
On the main backup screen you also have the option to download partial backups i.e. your home directory that contains all your files and emails, your databases, your email forwarder settings etc.
These partial backups have an advantage that they can be used by you to restore a portion of the site. Please note that Home Directory contains website files as well as email accounts. You can open the downloaded zip file and extract the files on your computer to find and restore individual files from it.
Backup Wizard
The Backup Wizard available under Files section does the same but it has a different work flow to make it easy for you to download and restore backup.
Hope this helps you keep regular backups of your important data. We cannot stress enough how important it is to keep regular backups and multiple backups. If you need any assistance with backups, please do not hesitate to contact us or you can post your comments and questions below.
MX Record for Email in cPanel
MX (Mail exchanger) record is a type of resource record in the domain name system that specifies which mail servers are responsible for receiving emails for the domain. You can read more about it at http://en.wikipedia.org/wiki/MX_record
When you order a web hosting account, by default your hosting server where your website is hosted also has a mail server. Therefore MX record is automatically created to specify your web hosting server to be the mail server as well and receive emails. That is why you can create and manage email accounts using cPanel interface, which directly interacts with the local mail server on that server.
However at times some clients want to host their email elsewhere. For this reason they will need to change the MX record so that emails can go that particular server. To change the MX, you can click on MX Entry in Mail section of cPanel. For some reason cPanel calls it MX Entry instead of MX Record.
Priority in MX Record
Since it is possible to have multiple mail servers configured to receive emails for a domain, the next screen explains how the priorities work MX records (entries).
- Lower values denote higher priority, with 0 being the highest possible priority.
- The primary mail server(s) (with the lowest-numbered priority) will receive mail sent to your domain.
- Secondary mail servers (those with higher priority values) can be used for backup or other purposes.
- If you assign multiple mail servers the same priority, then when that level of mail server is needed, mail will be distributed to those servers randomly.
You may have to select the domain from the drop down to proceed.
Email Routing
Once you select the domain, you will be presented with the current MX configuration of the domain. For example in this screen shot here we see that domain is configured to receive email on Local server. It is currently using “Automatically Detect Configuration” option to come up with that.
You can keep it as it is i.e. let cPanel automatically detect configuration, or you can choose one of the other three options. They are as follows:
Local Mail Exchanger: Configure local server to always accept mail. Mail will be delivered locally on the server when sent from the server or outside the server.
Backup Mail Exchanger: Configure server as a backup mail exchanger. Mail will be held until a lower number mail exchanger is available.
Remote Mail Exchanger: Configure server to not accept mail locally and send mail to the lowest MX record.
Please be careful with changing this. The Warning is pretty clear: Setting the wrong option here can break receiving mail on your server. If you are at all unsure about which option to select contact your system administrator (that is our support).
You can click on Change button to make the change (if required).
Since there can be multiple MX records in a domain, you can see the listing of your current MX Record(s). You have the option to edit or delete the record:
If you click Edit, it you can modify the Priority or Destination:
Or you can add a new record as well:
Once you are done with the changes, you can see that all the records under MX Records section are what you needed to set. It may take a few hours before the DNS updates propagates and new email starts delivering on the MX records for your domain.
Hope this tutorial makes it easy to manage MX records for your domain. If you need help with it, please feel free to contact us or you can post in the comments section below.
