[downloadsmasti]

Hi

Can some one help me in taking backup from my vps

Host : Knownsrv

i tried in many way i have a cpanel on it i tried with cpanel backup also and it was not succeeded i even contacted cpanel team and they mentioned

I/O speed is soo slow and server is getting un responsive while trying . They even tried a force backup it started but its been two days still not completed they informed me it will not complete as due I/O slow speed and memory is also going 100% all the time

i even tried with SSH for a cpmove it also got an error at last after 3 hrs of time it has given this error "ERROR: tar of archive returned error -1"

so now i wanna have a backup and restored in another host

i even sent a ticket to knownsrv but still haven't got any reply

can some one help me in taking a backup and restoring

1.The main problem is that your VPS container is totally out of memory:


root@server1 [/usr/local/cpanel/logs]# cat /proc/user_beancounters
-bash: fork: Cannot allocate memory
root@server1 [/usr/local/cpanel/logs]# free -m
-bash: fork: Cannot allocate memory
root@server1 [/usr/local/cpanel/logs]#


I did notice that you had "Backup Accounts" disabled in Main >> Backup >> Configure Backup. I enabled that option, but then I noticed that a backup process would not even start when I selected the function in cPanel. I noticed that this was a VPS, so I tried to look at /proc/user_beancounters, which reports on VPS limits, but as you can see the VPS is so far out of memory that it cannot even view a simple file.

You will need to ask your VPS administrator to increase the memory allocated to this VPS. It has no memory available to carry out even very simple tasks.

===============================================

2.There is nothing that I can do in this situation right now. I cannot even run basic shell commands. I showed you what happens when I try to use simple commands like less. You need to ask your VPS provider to, at a minimum, reboot the server, and if possible, increase the memory allocation.

==============================================

3.I was able to login now, and it appears the server has been rebooted again. The IOWait is already hitting 100% just as I look at small files, and this is without even attempting to run backups. This can cause a lot of problems and indicates that the disk simply cannot keep up with the demand from this and other VPSes on the same hardware node. There is unfortunately nothing I can do about this, as only your VPS provider can move you to better hardware/resources.

That said, I was able to start the backup process with

/scripts/cpbackup --force

The force was neccessary as backups are not even scheduled to run today. They immdiately paused though, as the load is too high due to the IO wait I mentioned earlier. Currently it is stuck on

Waiting for load to go down to continue


As the load does not seem to be going down, it's possible this backup may never complete. You can raise this limit by setting "Extra cpus for server load" in tweak settings which will force it to run even when the load is high (and thus make the load even higher), but the real issue is that the disk is just too slow on this system.

they should shut down http and mysql so backups can be taken
it's under attack and the host isn't capable of blocking it, a lot of people complained about knownsrv to me and the only thing I can offer is a 10% discount on wrzhost

Sorry to say i already bought from another host and is their any solution to take backup and restore to cpanel account

if you have a copy of the site script ... then you can take only backup of MySQL of the site only

i tried only mysql backup with this

mysqldump --opt -u[DB-USERNAME] -p[DB-USER-PASSWORD] DBNAME > backup.dump

but got an error timed out message in SSH and after that never completed

No reason to explain for 100% memory i was with same specs wity them from 8 months and haven't got any problem before for taking a backup

You can try mysqldumper its a free script

Mysqldumper works great on big DBs also but I think his resource issues will not allow it to run, especially the memory usage spiking to 100%.

Hello there,

Seems like you have root access to the server, so I would suggest you stop all unneeded services (web, mail, ftp services), then create your backup. This way you are not fighting for resources from other services.

Make a archive of the files in public_html and export the DB from phpmyadmin.
This is enough to restore your account on new server.
