CPanel Server Backup Drive
May 3, 2008
After adding a second drive mounted as /home2 for backups I attempted to use the cPanel "Configure Backup" and I get the following message.
Quotas cannot be built!
Your cpbackup destination is on a filesystem which has quotas enabled.
Please move it to a filesystem which does not have quotas turned on
or a separate partition/disk slice mounted at /backup.Backup has been
disabled to prevent quota problems...
All searches on how to resolve this really reveal no solutions.
I did a google search on "disable filesystem quota" among others and could
find nothing.

We are limited with a maximum of 2 drives per server, with a maximum of 750gb drives.
We are thinking of going with 2 500gb hard drives. However the question is, should we use the Secondary drive with Raid 1 and let our VPS clients worry about their own backups or should we instead just use the secondary drive as a backup drive and backup each VPS nightly?

As I have never used cPanel neither have whatsoever experience with control panels, in the process of ordering a couple of new server I am wondering what's the average recovery time after a server failure which involves data (ie. disk failure).
I am interested to understand this, because I need to choose between hardware raid or backup disk.
For example, at LiquidWeb (this is just one of the many managed providers i am evaluating) you can pay the same server 264$ with 2x250 hardware raid 1, and 219$ with 2x250 simple hard drives, where the second one is supposed to be a backup drive.
I am yet to ask, but on this servers most likely (at this prices) they do not have hot swappable disk drives where they can rebuild the array "live", so also if i choose raid hardware, in case of a disk failure, i face a downtime to bring down the server, rebuild the array, bring on the server, which I guess is something not less than 30-60 minutes downtime.
The advantage of this solution is that a disk failure keeps the system running, so you can schedule a maintenance window to replace the disk and rebuild the array, I guess.
On the other side, relying on a backup disk (and of course rsyncing data to an offsite server, i would do this anyway) you save 45$ each month, and disks after all do not fail every month.
If the main disk fails, they need to replace the disk, install again the server with what I suppose being a standard image (so let's figure a couple of hours, as they have a 30min hardware replacement sla), then you need to restore backups (which in my case are something like 20gigs). So I guess, on an average, it would take something like 4 hours downtime.
Am I correct ?
What would you reccomend as a solution with cpanel, taking into account the huge price difference ? Backup drive or Hardware raid ?
This would be for a single big website, not a hosting-company with resellers and customers environment, so I would value more the monthly saving, rather than the high availability, but of course I am interested to know what is the average time to recover a cpanel server after a drive failure.
Besides I have also another question, as I have never had a colocated server with raid hardware, so i do not know anything about this.
When a drive fails in a raid1 hardware environment, how the hosting provider gets notified ? I suppose it's not a led on the server to blink, as no one would see it.
So if you have software raid (like my computer at home) you get an email from mdadm with "warning, array degraded", so you know it quick and you can check it anytime doing a ' cat /proc/mdstat '. What about hardware raid?
My fear is that nobody notices my raid1 drive failure, the server keeps going on just a drive, then maybe the other drive fails, and it would be unpleasant: while a single drive failure would be obviously very easy to spot for me.

My hosting company is offering to sell me backup space which will be mounted as a network location. e.g. /usr/local/backup
My question is how would I use this since Plesk seems to be configured either to use an FTP location or to use the server repository. Would I have to change the location of the server repository to this network location? This doesn't seem ideal.
Plesk 11.5 on CentOs 6.4

we have a thumb drive attached to a CentOS (linux) box and mysql backups are automatically saved to the thumb drive. Is there a way an HOW to automatically purge backup files if they are older than say 15 days? I suppose I would need to write a script for this and place it in the cron scheduler.
The format of the mysql dump files are:
Backup_20070420_0015.sql

1- i did Os Reload with new Hard drive for "home"
2- data "backups" drive lost
3- replaced the old home drive as "/old drive"
4- " /old drive " is now the secondry drive in my server and it has the all sites usres and evry thing
5- what i need , to trasfer, copy this sites from " /old drive " to "home"
but data center said
The /olddrive/home directory contains the contents that were previously in the /home directory. You can copy files from this directory to any other directory on your server.
The command to copy files in the UNIX environment is the "cp" command.
The user directories in /olddrive/home directory contain the web page files for the users. However, simply copying the contents over will not recreate the users or domain entries in DNS/httpd. If you wish these back you will need to recreate them manually or restore them from backups.

Primary drive (centos/cpanel) is corrupt
The server is displaying these errors when I tried to do an FSCK:
Bad inode IO
ext3-fs error (device(8,3)) IO Failure
I am having a new primary installed and old primary set as 2nd drive. I need to recover the cpanel domain accounts from this 2nd drive after I mount it with the method below:
mkdir /backup
mount /dev/sdb1 /backup
However, how do I actually recover these accounts in an automated process via whm? I've done this before with the same matter (corrupt primary drive, mount as 2nd, etc) but cannot exactly remember the proper steps.

I just purchased a brand new 10K 150GB drive. How can I take an exact copy of my current drive and transfer everything over to the new drive? I think I need to create a snapshop, or mirror it somehow.
What software will do this? I was told trueimage, but its very pricy, is there anything else?

How should I go about the backup of my cpanel server.
I have 2x 250gigs drive in raid 1 + 1x 250gigs hd mounted as /backup
I also need offsite backup.
Im reading, and im a bit confuse how I should approach this backup thing.
Here are a few of my questions:
1) Should I use the built in cpanel backup or a different script?
2) With offsite backup, rsync seems to be the way to go?
3) If I have a 250gigs drive as /home, it seems that my /backup drive needs to be way larger to accept daily / weekly / monthly backup?
4) Is offsite also needs daily /weekly / monthly backup?

Example: I have 1 server for hosting, 1 server as Dedicated Backup server
(Pls don't recommend me outsourced backup server as I already got one)
I am looking for a solution which I am able to do daily backup while keeping low server load as well as able to restore it quickly when I need it. It's a cpanel servers.
I understand that CPanel own backup method will tar my files (but I have too many accounts) and it also takes a lot of my server CPU resources which slows down my hosting server.
I am now using rsync which does incremental backup that really works and I am happy about it but I paid $55 per month for 1 cpanel servers as I oursourced the rsync installation & server management backup. I have few servers and I don't find it cost effective.
Anyone here can suggest different kind of method which I have not known yet? Or I would really appreciate if someone do not mind to share installation procedure for rsync with me. I tried to google for it and find them all very shallow information. This is not a try-and-error.

I have a crucial database (mysql).
My server is running cpanel. It has daily backup but it is not enough as it is running a lot of transaction daily.
I would like to run the backup to backup database only every 30 mins using cronjob. How do i do that in crontab. I have root access to the server.

I have a dedicated box and I started getting Input/output errors today.
I tried:
# fsck
fsck 1.40-WIP (14-Nov-2006)
e2fsck 1.40-WIP (14-Nov-2006)
/dev/hda2: recovering journal
fsck.ext3: unable to set superblock flags on /dev/hda2
then I tried:
# fsck -a -t ext3 /dev/hda2
fsck 1.40-WIP (14-Nov-2006)
/dev/hda2: recovering journal
fsck.ext3: unable to set superblock flags on /dev/hda2
My data is backed up, so was going to ask for a reimage, but is this an indication of bad hardware? Should I ask for a replacement drive? Is there anything else I should try on my own before going to the host?

I want to back-up accounts managed by cPanel/WebHostManager to a remote server. I want to be able to restore to any of the last 7 days. I believe doing an incremental back-up each night can accomplish this best, saving both bandwidth and disk space on the remote server.
Using the back-up functionality built into WHM is appealing because WHM knows what files need to be backed up to do a full restore. However, WHM can't do exactly what I'm looking for either. I've been looking into using rsync as described in this document:
[url]
It looks becaue of the "hard link" capabilities of linux, rsync can be used to create what functions like a full back-up every night but requires a full backup the first day and then each day after that only the incremental changes have to be transfered. However, because I don't know what directories need to be backed up, I'm not sure how to implement an rsyc solution either. (BTW, I want to back-up everything necessary to be able to restore each account except the log files. So, that means MySQL, mail, config info, and whatever the user has uploaded)
