## 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
|
|
```

## 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)
|
|
```
|
|
|

## 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
|
