title: Back up and recover your Tiger Cloud services | ||
excerpt: See how and when Tiger Cloud backs up your data, making sure you always have something to fall back on in case of disaster recovery | ||
products: [cloud] | ||
keywords: [backups, restore] | ||
tags: [recovery, failures] | ||

# Back up and recover your $SERVICE_SHORTs | ||
|
||
$CLOUD_LONG automatically handles backup for your $SERVICE_LONGs using the `pgBackRest` tool. You don't need to perform backups manually. What's more, with [cross-region backup][cross-region], you are protected when an entire AWS region goes down. | ||
|
||
$CLOUD_LONG automatically creates one full backup every week, and | ||
incremental backups every day in the same region as your $SERVICE_SHORT. Additionally, all [Write-Ahead Log (WAL)][wal] files are retained back to the oldest full backup. This means that you always | ||
have a full backup available for the current and previous week: | ||
|
||
 | ||
|
||
In the event of a storage failure, a $SERVICE_SHORT automatically recovers from a backup | ||
to the point of failure. If the whole availability zone goes down, your $SERVICE_LONGs are recovered in a different zone. In the event of a user error, you can [create a point-in-time recovery fork][create-fork]. | ||
|
||
## Enable cross-region backup | ||
|
||
<Availability products={['cloud']} price_plans={['enterprise']} /> | ||
|
||
For added reliability, you can enable cross-region backup. In this case, you have two identical backups of your $SERVICE_SHORT at any time, but one of them is in a different AWS region. | ||
|
||
You enable cross-region backup when you create a $SERVICE_SHORT, or configure it for an existing $SERVICE_SHORT in $CONSOLE_LONG: | ||
|
||
<Procedure> | ||
|
||
1. In [$CONSOLE_SHORT][console], select your $SERVICE_SHORT and click `Operations` > `Backup & restore`. | ||
|
||
1. In `Cross-region backup`, select the region in the dropdown and click `Enable backup`. | ||
|
||
 | ||
|
||
You can now see the backup, its region, and creation date in a list. | ||
|
||
</Procedure> | ||
|
||
You can have one cross-region backup per $SERVICE_SHORT. To change the region of your backup: | ||
|
||
<Procedure> | ||
|
||
1. In [$CONSOLE_SHORT][console], select your $SERVICE_SHORT and click `Operations` > `Backup & restore`. | ||
|
||
1. Click the trash icon next to the existing backup to disable it. | ||
|
||
 | ||
|
||
1. Create a new backup in a different region. | ||
|
||
</Procedure> | ||
|
||
|
||
## Create a point-in-time recovery fork | ||
|
||
To recover your $SERVICE_SHORT from a destructive or unwanted action, create a point-in-time recovery fork. You can recover a $SERVICE_SHORT to any point within the period [defined by your pricing plan][pricing-and-account-management]. The original $SERVICE_SHORT stays untouched to avoid losing data created since the time of recovery. | ||
|
||
Since the point-in-time recovery is done in a fork, to migrate your | ||
application to the point of recovery, change the connection | ||
strings in your application to use the fork. The provision time for the | ||
recovery fork is typically less than twenty minutes, but can take longer | ||
depending on the amount of WAL to be replayed. | ||
|
||
To avoid paying for compute for the recovery fork and the original $SERVICE_SHORT, pause the original to only pay storage costs. | ||
|
||
You initiate a point-in-time recovery from a same-region or cross-region backup in $CONSOLE_LONG: | ||
|
||
<Tabs label="Point-in-time recovery in Tiger Cloud Console"> | ||
|
||
<Tab title="Same-region backup"> | ||
|
||
<Procedure> | ||
|
||
1. In [$CONSOLE][console], from the `Services` list, ensure the $SERVICE_SHORT | ||
you want to recover has a status of `Running` or `Paused`. | ||
1. Navigate to `Operations` > `Backup & restore` and click `Create recovery fork`. | ||
1. Select the recovery point, ensuring the correct time zone (UTC offset). | ||
1. Configure the fork. | ||
|
||
You can add an HA replica, enable cross-region backup, change the compute resources, and | ||
add a connection pooler as part of this process. Best practice is to match | ||
the same configuration you had at the point you want to recover to. | ||
1. Confirm by clicking `Fork service`. | ||
|
||
A fork of the $SERVICE_SHORT is created. The recovered $SERVICE_SHORT shows in `Services` with a label specifying which $SERVICE_SHORT it has been forked from. | ||
1. Update the connection strings in your app to use the fork. | ||

Cross-region backups are identical replicas of your $SERVICE_SHORT, but one of them is in a different AWS region --> this reads like you have multiple cross-region backups per service, which is not the case. Also I wanted to clarify that you don't create cross-region backup once and it stays the same - it gets updated daily and weekly just like the regular backup, so at any point in time you have two identical ones - cross and same-region.
