# Backup restore
## Create a backup of the GitLab system
A backup creates an archive file that contains the database, all repositories and all attachments.
This archive will be saved in backup_path (see `config/gitlab.yml`).
The filename will be `[TIMESTAMP]_gitlab_backup.tar`. This timestamp can be used to restore an specific backup.
You can only restore a backup to exactly the same version of GitLab that you created it on, for example 7.2.1.
```
# use this command if you've installed GitLab with the Omnibus package
sudo gitlab-rake gitlab:backup:create
# if you've installed GitLab from source or using the cookbook
bundle exec rake gitlab:backup:create RAILS_ENV=production
```
Example output:
```

## Upload backups to remote (cloud) storage
Starting with GitLab 7.4 you can let the backup script upload the '.tar' file it creates.
It uses the [Fog library](http://fog.io/) to perform the upload.
In the example below we use Amazon S3 for storage.
But Fog also lets you use [other storage providers](http://fog.io/storage/).
For omnibus packages:
```ruby
gitlab_rails['backup_upload_connection'] = {
'provider' => 'AWS',
'region' => 'eu-west-1',
'aws_access_key_id' => 'AKIAKIAKI',
'aws_secret_access_key' => 'secret123'
}
gitlab_rails['backup_upload_remote_directory'] = 'my.s3.bucket'
```
For installations from source:
```yaml
backup:
# snip
upload:
# Fog storage connection settings, see http://fog.io/storage/ .
connection:
provider: AWS
region: eu-west-1
aws_access_key_id: AKIAKIAKI
aws_secret_access_key: 'secret123'
# The remote 'directory' to store your backups. For S3, this would be the bucket name.
remote_directory: 'my.s3.bucket'
```
If you are uploading your backups to S3 you will probably want to create a new
IAM user with restricted access rights. To give the upload user access only for
uploading backups create the following IAM profile, replacing `my.s3.bucket`
with the name of your bucket:
```json
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "Stmt1412062044000",
"Effect": "Allow",
"Action": [
"s3:AbortMultipartUpload",
"s3:GetBucketAcl",
"s3:GetBucketLocation",
"s3:GetObject",
"s3:GetObjectAcl",
"s3:ListBucketMultipartUploads",
"s3:PutObject",
"s3:PutObjectAcl"
],
"Resource": [
"arn:aws:s3:::my.s3.bucket/*"
]
},
{
"Sid": "Stmt1412062097000",
"Effect": "Allow",
"Action": [
"s3:GetBucketLocation",
"s3:ListAllMyBuckets"
],
"Resource": [
"*"
]
},
{
"Sid": "Stmt1412062128000",
"Effect": "Allow",
"Action": [
"s3:ListBucket"
],
"Resource": [
"arn:aws:s3:::my.s3.bucket"
]
}
]
}
```
## Storing configuration files
Please be informed that a backup does not store your configuration files.
If you use an Omnibus package please see the [instructions in the readme to backup your configuration](https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/README.md#backup-and-restore-omnibus-gitlab-configuration).
If you have a cookbook installation there should be a copy of your configuration in Chef.
If you have a manual installation please consider backing up your gitlab.yml file and any SSL keys and certificates.
## Restore a previously created backup
You can only restore a backup to exactly the same version of GitLab that you created it on, for example 7.2.1.
```
# Omnibus package installation
sudo gitlab-rake gitlab:backup:restore
# installation from source or cookbook
bundle exec rake gitlab:backup:restore RAILS_ENV=production
```
Options:
```
BACKUP=timestamp_of_backup (required if more than one backup exists)
```
Example output:
```
Unpacking backup... [DONE]
Restoring database tables:
-- create_table("events", {:force=>true})

## Configure cron to make daily backups
For Omnibus package installations, see https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/README.md#scheduling-a-backup .
For installation from source or cookbook:
```
cd /home/git/gitlab
sudo -u git -H editor config/gitlab.yml # Enable keep_time in the backup section to automatically delete old backups
sudo -u git crontab -e # Edit the crontab for the git user
```
Add the following lines at the bottom:
```
# Create a full backup of the GitLab repositories and SQL database every day at 4am
0 4 * * * cd /home/git/gitlab && PATH=/usr/local/bin:/usr/bin:/bin bundle exec rake gitlab:backup:create RAILS_ENV=production
```
