95th And Backup
May 22, 2007How do you deal with off-site backups on a colo machine billed at 2 Mbps 95 percentile?
Moreover, do you do any httpd throttling so a few spikes don't really hurt you on the 95% billing method?

I have a question about 95th percentile billing. Say I have a 6mbit commit. That means I should be getting 2000GB/month. I calculated that if I burst 100mbit until I get 2000GB then do no bandwidth for the rest of the month, I would get charged for 100mbit of commit, is this correct?
Calculations
2000000MB * 8 = 16000000 mbits / 100mbit = 160000 seconds / 60 = 2667 mins / 60 = 44.4
So 44.4 hours of 100mbit equals 2000GB.
Now lets say they take a snapshot every 5 mins.
44.4 hours * 60mins = 2666 / 5 mins per snapshot = 533 snapshots
Now lets find the total number of snapshots in a month.
30 days * 24 hours * 60 minutes / 5 minutes per snapshot = 8640 snapshots
Now we find 95th percentile
8640 * .95 = 8208
8640 - 8208 = 432
So 432 snapshots will be dismissed as burst, but I will have 533 snapshots at 100mbit (as calculated above).
95th percentile...
what is it?
Is it possible to have a 40Mbps 95th percentile, but only push 3TB in a month?
I know 40Mbps=~12,000GB, that's why it doesn't make sense.
Basically provider offers 2000gb bandwidth.
However, at the end of the month they don't look at the total X GB's transfered, they measure it up with 95th percentile.
I know there's a formula involved, but maybe someone can give me some insight on why 95th is for, and the formula of course would help
100mbps can be rather vague at first so I will now try breaking 100mbps, - my question will be near the bottom.
Ive used a conversion calculator to draw this up.
8192 Mbit (Megabits) = 1 GB (GigaByte)
100 Mb (Megabits) = 0.01220703125 (GigaBytes)
So, to reach 1 GB it will take just under 1 min 22 seconds at a rate of 100mbps.
8192 Mbit / 100 Mbit = 81.92 seconds which is 1 min 21.92 seconds.
1 min 21.92 seconds = 1 GB.
My question:
As i am more familiar dealing with Gb's more so than Mbits i have a few questions which i am not so sure about .....
On the 95th percentile model, I recall reading bursting not calculated for 36 hrs in this model.
In our application, for now, we will only be uploading to the colocation 6 days a week, on a 10 meg upstream - averaging anywhere from 2 hrs nightly to Saturday ....real small upload.
When I look at 95th percentile, I am looking at it that we would be billed at 9Mbps if we were to utilize this billing method as opposed to purchased transit.
some light on the math & or the *36 hr* burstable bandwidth ?
I have Munin running on my Centos 5.2 box, but would like the 95th percentile calculations. I have found this page for an add on:
[url]
where to put this code and/or how to install it?
Just curious about what kind of pricing people have been able to get when going for 95th percentile billing, and what kind of quantities?
For example, currently we are paying $44/Mbps for a quantity of 250Mbps, so $11k/month for roughly 100TB of transfer.
Does that seem like a really high price?
Why do seemingly most companies do 95th percentile billing based on a 5 minute polling interval?
Do you think there would be any complaints about basing 95th percentile billing on a 1 minute polling interval?
I just had a quick question, I have been using dedicated servers for a long time now, and I was just looking to host one of my own 1U servers that I have been using at home, now I had a simple question, but it seems to confuse me on what exactly do I pay at the end of the month.
I have read about the 95th percentile billing, and paying for 1Mbps.
I usually had 1000GB with my servers, simple, easy.
All I need to know is if I get 1Mbps, can I not go over that 1Mbps while backing up files, or hosting a game server? or is it that I have a certain amount of bandwidth because this is really confusing me.
I have multiple backups stored under server repository (subscriptions --> <domainname> --> website and domains --> backup manager).
The physical files are located at: /var/lib/psa/dumps/clients/904279/domains/<domainname>/
When I click the green arrow to download these files to a local computer (see attached image) I get a new page with title "Download the backup file". On this page I have the option to set a password on the downloaded file, but no matter what I do (password or no password) the file is not downloaded to my local PC. I don't get a pop-up box with the option to save the file. Just nothing happens ...
I have 2 problems:
Firstly I wonder if there is any possibility to limit the number of cores the plesk backup zipping tool uses? This pigz takes up all my CPU. Is there any way I can reduce the amount of cores it uses because all my websites are down every time a backup takes place for around 3 minutes.
Secondly I get the following in my syslog:
1 baby plesk sendmail[20189]: Error during 'check-quota' handler
I don't know what is wrong. I think it's since the upgrade to Plesk 12. I now have 12.0.18 Update #13.
I have a 6GB backup file created with another Plesk Backup Manager, now I trying to upload this backup file to my Plesk Backup Manager but after upload 3% I am getting "413 Request Entity Too Large" error, I tried with disable NGINX but still getting this error.
how can I resolve this error or is their any other way to upload my file on backup manager?
I see that Backup Manager have a file size restriction of 2GB how can I increase this?
I have an Ubuntu 14.04 LTS 64 bit virtual private server with Plesk 12. The server is hired from a hosting provider. The server is used to run the Odoo ERP application (using postgres database).
The Odoo application is running fine and now I want to create a backup of the application using Plesks Backup manager.
I choose configurations and content option in the backup manager but the created backup is only 200kb.
I think the problem is the location where the Odoo application is installed is not included in the backup. I made a tar backup from the server and extracted it on my pc. It seems that the main parts of the Odoo application are in the var, opt, etc and usr directories (not in a domain but under root).
Installing the application in a domain would solve the Plesk backup issue I think but the installation script of Odoo puts Odoo in var, opt, etc and usr directories even if I put the install script in the directory of a created domain. Since the manual Odoo installation is complicated I am very happy to use the script.
My questions are:
1. Is it possible to include the directories var, opt, etc and usr in the Plesk backup and how and where do I do that?
2. Can I restore such a backup without no problem in Plesk?
I current do some rsync backups with a command like so every day
rsync -az -e ssh --stats --delete --exclude "stuff" / user@server:/home/user/
What I want to do is have some incremental backups in there in subdirectories. So, for example, something like this on the remote server
/home/user/something.tuesday
/home/user/something.friday
I thought the --backup --backup-dir Switches were used to store just the files that had changed in seperate directories, am I wrong on that?
I've read everything I could find, including the big rsnapshot scripts, but I'm not able to do what I want, it seems so simple but something's not right, am I wrong that subdirs should have just files that are new or have changed. I tried various things like this, but had no luck
rsync -az -e ssh --stats --delete --backup --backup-dir=/home.Thursday --exclude "stuff" / user@server:/home/user/
I have transfer full backup with cpanel to ftp backup,
But,How transfer full backup from FTP Backup to cPanel?
Whitch software?
my cpanel doesn't get backups. When I force it, it gives me this error:
mount: can't find /backup in /etc/fstab or /etc/mtab
mount: can't find /backup in /etc/fstab or /etc/mtab
[cpbackup] Backup failed! /bekkaplars is not mounted! at /scripts/cpbackup line 415.
It's a vps. Another interesting thing is, my other 3 vpses run good even /etc/fstab has no line like /backup in there, also.
I would like to weight the benefits and costs of using remote backup and local backup to another hardisk? Let's assume the price is the same.
What's the benefits of using remote backup?
Is it secured to use local backup in another hardisk?
I'm running on linux centos.
What happend if hacker get hold of my server?
Currently, i have 80GB of diskspace. Does it mean i will need at least 80GB of ANOTHER hardisk to backup that?
How To take Backup in a Reseller account..I have over 54 account in an Reseller hosting ..i don't have ssh ..then how can i take full backup of all the account... any idea ..the Server is REDHAT Enterprise 3 With WHM 11.23.0 cPanel 11.23.1...
