On-site and off-site backups differ in where the backup is stored. An on-site backup is kept on the same server or infrastructure as your website, while an off-site backup is stored somewhere separate — a different server, a cloud storage service, or your own computer. The crucial difference is safety: an on-site backup can be lost by the same failure that hits your site (a server crash, a hack, an account problem), whereas an off-site backup survives such events. That is why off-site backups are far safer, and why keeping at least one off-site copy is a core principle of protecting your site.
This guide explains what each type is, why off-site backups are safer, and how to make sure at least one of your backups lives off-site.
Did you know?
A backup stored on the same server as your site can vanish in the very disaster you are backing up against. The whole point of an off-site backup is that it is not there when the server goes down.
What on-site backups are
An on-site backup is a backup stored on the same server or hosting infrastructure as your live website. When your host creates a backup and keeps it on the same account or server, or when you save a backup to your hosting space, that is an on-site backup — it lives alongside the site it is protecting.
On-site backups are convenient and quick to create and restore, since everything is in one place. But that convenience comes with a serious catch: because the backup is on the same infrastructure as the site, anything that takes out the site can take out the backup too, which limits how much protection an on-site backup really offers.
What off-site backups are
An off-site backup is stored separately from your website’s server — on different infrastructure entirely. This could be a dedicated backup service, cloud storage, another server, or your own computer. The defining feature is separation: the backup is not on the same machine or account as your live site.
This separation is what makes off-site backups safe. Because the backup lives elsewhere, a disaster that affects your site’s server — a crash, a hack, a data-centre problem, or an account issue — does not touch the off-site copy. So when you most need a backup, an off-site one is still there and unaffected.
Why off-site backups are safer
The core reason off-site backups are safer is that they survive the failures on-site backups do not. Consider the scenarios: a server hardware failure, a serious hack that compromises the whole account, a data-centre disaster, or losing access to your hosting account. In each of these, an on-site backup could be lost along with the site — but an off-site backup, stored elsewhere, remains safe.
This is the whole point of backing up: to have a copy that survives whatever goes wrong. A backup that can be destroyed by the same event as the original offers only partial protection. Off-site storage removes that weakness, ensuring your backup is genuinely a fallback rather than a second copy in the same fragile place.
On-site vs off-site at a glance
Here is how the two compare.
On-site backups are convenient but vulnerable to the same failures as your site; off-site backups are the safe, resilient choice.
The best practice: keep an off-site copy
The core backup principle here is simple: always keep at least one backup off-site. On-site backups are fine as a convenient first line — quick to make and restore for everyday recovery — but they should never be your only backup, because they share the fate of your site.
So the best practice is to ensure at least one of your backups is stored off-site, separate from your hosting. That off-site copy is your real insurance, the one that survives the worst-case scenarios. Whether it is a backup service, cloud storage, or a downloaded copy on your own computer, having that separation is what turns backups from a hopeful gesture into genuine protection.
How to get an off-site backup
There are several easy ways to keep an off-site backup. Some hosts store backups off-server by default (worth checking). You can use a backup service or plugin that sends copies to cloud storage (like a cloud drive), or you can periodically download a backup of your files and database and keep it on your own computer or a separate cloud account.
The simplest habit for many is to download a backup regularly and store it somewhere away from your host. Combined with any on-site or host backups for convenient everyday recovery, that off-site copy ensures you are protected against even the failures that would wipe out on-site backups. Set it up once, keep it current, and your site’s data is genuinely safe.

FAQs
What is the difference between on-site and off-site backups?
It is where the backup is stored. An on-site backup is kept on the same server or infrastructure as your website; an off-site backup is stored separately — a different server, cloud storage, or your computer. Off-site backups survive failures that would destroy on-site ones, making them far safer.
What is an on-site backup?
An on-site backup is stored on the same server or hosting infrastructure as your live website. It is convenient and quick to create and restore, but because it lives alongside the site, anything that takes out the site — a crash, hack, or account problem — can take out the backup too.
What is an off-site backup?
An off-site backup is stored separately from your website’s server — on a backup service, cloud storage, another server, or your own computer. Its separation means a disaster affecting your site’s server does not touch it, so it is still there and safe when you most need it.
Why are off-site backups safer?
Because they survive the failures on-site backups do not — a server crash, a serious hack, a data-centre disaster, or losing access to your hosting account. An on-site backup can be lost along with the site in these cases, while an off-site copy stored elsewhere remains safe and recoverable.
Should I keep backups off-site?
Yes — always keep at least one backup off-site. On-site backups are fine as a convenient first line for everyday recovery, but they share the fate of your site, so they should never be your only backup. An off-site copy is your real insurance against worst-case scenarios.
How do I make an off-site backup?
Some hosts store backups off-server by default (check yours). You can use a backup service or plugin that sends copies to cloud storage, or periodically download a backup of your files and database to your own computer or a separate cloud account. The key is storing it away from your host.
The bottom line
On-site and off-site backups differ in where they are stored: on-site on the same server as your website, off-site on separate infrastructure. That difference is decisive for safety — an on-site backup can be lost by the very failure it is meant to protect against (a crash, hack, or account problem), while an off-site backup, stored elsewhere, survives such events.
So while on-site backups are convenient for everyday recovery, they should never be your only copy. The core principle is to always keep at least one backup off-site — via a backup service, cloud storage, or a downloaded copy on your own computer. That off-site copy is your real insurance, turning backups from a second copy in a fragile place into genuine protection against the worst.
