README
PHP client for restic backup tool. This library provides a simple way to create and manage backups with restic. It uses repositories as storage for backups.
Requirements
- PHP 8.1 or higher
- Composer
- Restic as binary or installed on the system, see https://restic.readthedocs.io/en/stable/020_installation.html
- Restic version 0.15.0 or higher
Installation
composer require muckiware/restic
Usage
How to use the library. This php client interacts with the restic binary to create, manage and restore backups in and of a repository. The first step is always to create a backup repository as storage for the backup data. After that, you can create backups in this repository and check the backup data. And at least if its necessary, you can restore the backup data.
Create a new backup repository
You will need first the backup object of the library, for to use the createRepository method. Import this class with use MuckiRestic\Library\Backup;
. The Backup-class has a static create
-method for to get the Backup object, like this $backupClient = Backup::create();
. With this create, you have access to all the Backup methods. The $backupClient->createRepository()
method initialize a new repository and need the required parameters password and the repositoryPath. The repositoryPath is where the backup data will be stored and the password is used to encrypt the backup data. It's required for all operations on the repository. It has to be set by the two setting methods $backupClient->setRepositoryPassword('1234')
and $backupClient->setRepositoryPath('./path_to_repository')
Optionally you can set the path for the restic binary, with $backupClient->setBinaryPath('./bin/restic_0.17.3_linux_386')
. This is necessary if the restic binary is not installed in the local system.
The method createRepository()
returns the object ResultEntity
.
The method getOutput
of the object ResultEntity
returns the output of the restic command. If an error occurs, an exception will be thrown.
Example
<?php declare(strict_types=1); use MuckiRestic\Library\Backup; class BackupService { public function createRepository(): void { try { $backupClient = Backup::create(); $backupClient->setBinaryPath('./bin/restic_0.17.3_linux_386'); //optional $backupClient->setRepositoryPassword('1234'); $backupClient->setRepositoryPath('./path_to_repository'); echo $backupClient->createRepository()->getOutput(); } catch (\Exception $e) { echo $e->getMessage(); } } }
Create a backup
Next step, create a backup into the repository by using the method $backupClient->createBackup()
. Also, this method will returns the object ResultEntity
. The backup path is required for the backup operation. It has to be set by the method $backupClient->setBackupPath('./path_to_backup_folder')
.
Every backup process creates a new snapshot of the backup data in the repository. These snapshots are represented by an individually hash string.
Example
<?php declare(strict_types=1); use MuckiRestic\Library\Backup; class BackupService { public function createBackup(): void { try { $backupClient = Backup::create(); $backupClient->setBinaryPath('./bin/restic_0.17.3_linux_386'); //optional $backupClient->setRepositoryPassword('1234'); $backupClient->setRepositoryPath('./path_to_repository'); $backupClient->setBackupPath('./path_to_backup_folder');); echo $backupClient->createBackup()->getOutput(); } catch (\Exception $e) { echo $e->getMessage(); } } }
Check the backup
After the backup process, it makes sense to check the backup data. The method $backupClient->checkBackup()
will return the object ResultEntity
. The method getOutput
of the object ResultEntity
returns the output of the restic command simple as string. If an error occurs, an exception will be thrown.
Example
<?php declare(strict_types=1); use MuckiRestic\Library\Backup; class BackupService { public function createBackup(): void { try { $backupClient = Backup::create(); $backupClient->setBinaryPath('./bin/restic_0.17.3_linux_386'); //optional $backupClient->setRepositoryPassword('1234'); $backupClient->setRepositoryPath('./path_to_repository'); echo $backupClient->checkBackup()->getOutput(); } catch (\Exception $e) { echo $e->getMessage(); } } }
Manage backups
The library provides methods for to manage backups. Import this class with use MuckiRestic\Library\Manage;
.
Get list of snapshots
You can get list of all snapshots of a repository with the method $manageClient->getSnapshots()
. The method getSnapshots
returns the object ResultEntity
. The method getOutput
of the object ResultEntity
returns the output of the restic command simple as string. If an error occurs, an exception will be thrown.
Example
<?php declare(strict_types=1); use MuckiRestic\Library\Manage; class ManageService { public function getSnapshotList(): void { try { $manageClient = Manage::create(); $manageClient->setBinaryPath('./bin/restic_0.17.3_linux_386'); //optional $manageClient->setRepositoryPassword('1234'); $manageClient->setRepositoryPath('./path_to_repository'); echo $manageClient->getSnapshots()->getOutput(); } catch (\Exception $e) { echo $e->getMessage(); } } }
Remove snapshot by id
You can remove a snapshot of a repository by id with the method $manageClient->getSnapshots()
. The method getSnapshots
returns the object ResultEntity
. The method getOutput
of the object ResultEntity
returns the output of the restic command simple as string. If an error occurs, an exception will be thrown.
Example
<?php declare(strict_types=1); use MuckiRestic\Library\Manage; class ManageService { public function getSnapshotList(): void { try { $manageClient = Manage::create(); $manageClient->setBinaryPath('./bin/restic_0.17.3_linux_386'); //optional $manageClient->setRepositoryPassword('1234'); //required $manageClient->setRepositoryPath('./path_to_repository'); //required $manageClient->setSnapshotId('snapshot_id'); //required echo $manageClient->removeSnapshotById()->getOutput(); } catch (\Exception $e) { echo $e->getMessage(); } } }
Remove old snapshots
You can remove old snapshots of a repository with the method $manageClient->removeSnapshots()
. This is kind a like a cleanup run for the repository. The method removeSnapshots
returns as always the object ResultEntity
. The method getOutput
of the object ResultEntity
returns the output of the restic command simple as string. If an error occurs, an exception will be thrown.
This cleanup run needs to be setup with the keep-parameters, which defined the number of daily, weekly, monthly and yearly snapshots to keep. The method setKeepDaily(int $keepDaily)
, setKeepWeekly(int $keepWeekly)
, setKeepMonthly(int $keepMonthly)
and setKeepYearly(int $keepYearly)
are used to set the keep-parameters.
default keep-parameters
Parameter | value |
---|---|
$keepDaily | 7 |
$keepWeekly | 5 |
$keepMonthly | 12 |
$keepYearly | 75 |
More details about the keep-parameters you can find in the restic documentation https://restic.readthedocs.io/en/latest/060_forget.html#removing-snapshots-according-to-a-policy |
Example
<?php declare(strict_types=1); use MuckiRestic\Library\Manage; class ManageService { public function removeOldSnapshots(): void { try { $manageClient = Manage::create(); $manageClient->setBinaryPath('./bin/restic_0.17.3_linux_386'); //optional $manageClient->setRepositoryPassword('1234'); //required $manageClient->setRepositoryPath('./path_to_repository'); //required $manageClient->setKeepDaily(1); //optional $manageClient->setKeepWeekly(2); //optional $manageClient->setKeepMonthly(4); //optional $manageClient->setKeepYearly(5); //optional echo $manageClient->removeSnapshots()->getOutput(); } catch (\Exception $e) { echo $e->getMessage(); } } }
Restore a backup
You can restore a backup from a repository with the method $restoreClient->restoreBackup()
. The method restoreBackup
returns also the object ResultEntity
. The method getOutput
of the object ResultEntity
returns the output of the restic command simple as string. If an error occurs, an exception will be thrown.
As default the method restoreBackup
will restore the latest snapshot. Optionally you can set the snapshot hash with the method setRestoreItem(string $snapshotHash)
. The snapshot hash you can get from the method getSnapshots
.
Example
<?php declare(strict_types=1); use MuckiRestic\Library\Restore; class RestoreService { public function createRestore(): void { try { $restoreClient = Restore::create(); $restoreClient->setBinaryPath('./bin/restic_0.17.3_linux_386'); //optional $restoreClient->setRepositoryPassword('1234'); $restoreClient->setRepositoryPath('./path_to_repository'); $restoreClient->setRestoreTarget('./path_to_restore_folder'); $restoreClient->setRestoreItem('snapshot_hash'); //optional echo $restoreClient->createRestore()->getOutput(); } catch (\Exception $e) { echo $e->getMessage(); } } }
