How long does it take to backup your VPS?
Hello!
I just backed up a tiny LXC VPS which runs an email Message Transfer Agent (MTA). I imagined at least a couple of you guys might be interested in how long the backup job took. 
The VPS was stopped and offline during the backup, which isn't so good, but at least being stopped prevents files on the VPS from changing into a possibly inconsistent state during the time the VPS is being copied.
When I checked the log, I thought, "Whoa! Only six seconds to shut down the VPS, make the backup, and restart the VPS!! ? It's not a big VPS, but, still, that's fast!"
The six seconds includes just shutdown, backup on the node, and reboot. The time to copy the backup to a remote location wasn't counted.
Here's the log:
INFO: starting new backup job: vzdump XXX --mode stop --node Proxmox-VE --storage local --remove 0 --compress zstd

Maybe now might be a great time to backup your VPS? ? Please let me know how long your backup takes. . . .

Backups are for the paranoid.
I use my disaster recovery plan instead.
@yoursunny Wow! Great story! Thanks for posting it! ??

I checked on my server for the backup time of a larger VPS.
For a VPS running a remote desktop, several web browsers, and several IDEs, the log says:
Bearing in mind that the 75 seconds includes shutdown, making the backup, and rebooting, 75 seconds seems pretty fast.
How long does it take you to back up your VPS?

666 seconds.

Backups?
I do like Linus, upload my files to a FTP and let the Internet mirror it.

Here's my log:
I only backup some logs, and in fact those files are unimportant so I do this online.
It is around 35 seconds because it is a remote backup.
If my vps is down, umm, I cannot do anything other then wait now.
On the other hand, I won't lose anything important even my vps is down, so I can wait.
Still a big gap in the market for a good automated set and forget backup provider that does not charge the earth.
JetBackup for Linux is a really good option price & feature wise but CentOS 7 only.
Ottomatik.io is amazing but stupid expensive even when you bring your own storage.
What a tantalizing tidbit!
Want to share a bit about the software / procedure you are using for the backups, please?

My former neighbor across my former street had a full time job as merely one member of the team doing backups for a Big Corp whose name we'd all recognize. Wondering how much that team cost. . . .
I remember once reading a detailed paper by an engineer at Sun arguing that backups had to be made with dd because tar made too many errors. A couple of years ago I went looking for that paper and couldn't find it. Well, tar always has seemed to work okay for me. Maybe I should have had a backup of the paper!
I don't know whether my neighbor's team used dd or whether they tested restoring. I guess probably they did at least test restoring. One would have to, right?
I've tested restoring from the Proxmox-made backups on my server. In a few dozen tests, restore seems to work okay with basic sanity checks like looking around and just using the restored system for a couple of weeks. I haven't yet tried anything like systematic hashing and confirming all the restored files. I think @yoursunny gets those systematic checks automagically from keeping his files in Github.

Although it is true that JetBackup for Linux only supports CentOS 7 installations, I would like to note that JetBackup 5 for Linux supports installation on both CentOS 7 and CentOS 8 systems. This version also utilizes the brand new JetBackup 5 core which has proven to be our fastest, most versatile, secure, and reliable version yet.
Thank you for your support.
This is good but the reality is that CentOS is commonly chosen if you are using a control panel. You are now supporting CentOS 8 as you had to given you are so tied to cPanel.
People in the main use Ubuntu/Debian without panels on their VPS. I know many that would use Jetbackup for Linux but OS is the deal-breaker. I mean I would have purchased 15 licences a few months back if it had supported Debian. I had to go elsewhere.
And let's face it, with recent events CentOS is going to be even less popular going forward.
Most of my important stuffs are code, and they are on my laptop and synchronized with github.
I also use portable disks to backup some other stuffs on my laptop.
Hello!
That's just my proxmox hypervisor syncing backups to the proxmox backup server. The hypervisor is a Ryzen physical server, while the backup server is a small QNAP from 2011 (i think it only has 1g of ram?). They are connected together directly so to not pass through the network, and while that screen is referred to the hypervisor only, there's plenty of clients in the office using pbs client directly.
We also use Duplicati to backup Windows machines.
I am just learning to use vps. Installed Centos 8 and configured updates, iptables. Now before installing a control panel and litespeed, I want to take backup of the system and all the configurations and download the backup file to my pc so that if anything goes wrong when installing control panel, I could just upload backup and install centos, firewall and all configurations at once. How do I backup and download for this purpose?
I imagine people might need a bit more information in order to answer your question.
Whatever tools you used from your VPS provider to do the Centos 8 install also might have an option for the backup and restore.
But, without knowing what tools your provider is offering, it's not so easy for us to help you.
Maybe your best option might be to ask your provider how to use their system for the backup and restore?
On Proxmox, one can use the
Backup nowandRestorebuttons:I can copy the backup file from server local storage to inside your VPS, where you can download it. Uploading a backup and restoring from it can be managed similarly.
Proxmox also supports various other sophisticated automagic backup options.

I just checked my VPS dashboard and there is no option for backup/snapshot. Dashboard has the options to install OS and Control Panels like cPanel, Plesk.
I installed Centos 8 from the dashboard and I will install cPanel next. I guess I will be able to take backup from cPanel later. But before installing cPanel, I was just trying to take backup of the system if possible using command line or GUI.
Can I install Proxmox on my VPS and take backup? If yes, any tutorial link?
@KidRock
Full block level/image/snapshot backups of a VPS would have to be done outside the VM, so if the provider does not offer it, you have to look into file level backup.
Which means you backup all the essential files from within the running system and copy off-site. Restore would then have to be something like: Reinstall OS from panel/ISO, then restore files inside the running VPS.
(If you have databases, there's a few special scripts/routines/considerations.)
Full tutorials on VPS backup probably belong in a different thread. (I this there was an article or two in the LES blog a while back.)
@KidRock Sorry, but, no, installing Proxmox inside your VM will not get you what you want. This is because:
If our provider offers Rescue Mode, we might get "outside" our VM by booting in Rescue Mode.
Besides doing backups, I've also seen running qemu-kvm within Rescue Mode used to install provider-unsupported OSes such as OpenBSD and Plan 9.
Maybe we also might be able to get outside our VM from within our VM! 😃 We could boot our own OS image by running qemu-kvm inside our VM, perhaps on a memory based file system that we create. 😃
There is a great LES tutorial by Anthony Smith, Migrate a KVM VPS from one host to another - Easy Mode. For the use case here, maybe we could use
ddoversshas explained in Ant's tutorial to copy our VPS' filesystem to our local backup disk instead of to a second VPS.@KidRock says he is a beginner. This stuff might be somewhat advanced for a beginner. But perhaps it nevertheless might be at least interesting for a beginner to read.

Never really thought about how long it takes to be honest...
So I had to check my healthchecks.io reports:
They are "online" backups however, using a hacked together bash script and borg to write the backups to a remote repo (maybe 1GB a day in total).
