Backup Methods

The backupCreate method is used to create a backup of the data in a specified data store.

Syntax

jsonverse.backupCreate(dataName);
  • dataName (string): The name or identifier of the data store for which you want to create a backup.

Example Usage (With Promises)

const Jsonverse = require("jsonverse"); // Import the jsonverse package // Initialize the JSONDatabase instance const db = new Jsonverse({ dataFolderPath: "./MyData", // data directory logFolderPath: "./MyLogs", // logs directory activateLogs: true, // to enable the logs set this value to true }); // Create a backup of the specified data store using promises jsonverse .backupCreate("exampleData") .then(() => { console.log("Backup created successfully."); }) .catch((error) => { console.error("Error creating backup:", error); });

Example Usage (Without Promises)

const Jsonverse = require("jsonverse"); // Import the jsonverse package const jsonverse = new Jsonverse("./data"); // Initialize jsonverse with data folder path // Create a backup of the specified data store using a callback function jsonverse.backupCreate("exampleData", (error) => { if (error) { console.error("Error creating backup:", error); } else { console.log("Backup created successfully."); } });

The backupRestore method is used to restore data from a backup file into a specified data store.

Syntax

jsonverse.backupRestore(dataName, backupFileName);
  • dataName (string): The name or identifier of the data store to which you want to restore data.
  • backupFileName (string): The name of the backup file to restore data from.

Example Usage (With Promises)

const Jsonverse = require("jsonverse"); // Import the jsonverse package const jsonverse = new Jsonverse("./data"); // Initialize jsonverse with data folder path // Restore data from a backup file into the specified data store using promises jsonverse .backupRestore("exampleData", "backup_20230906120000.json") .then(() => { console.log("Data restored from backup successfully."); }) .catch((error) => { console.error("Error restoring data from backup:", error); });

Example Usage (Without Promises)

const Jsonverse = require("jsonverse"); // Import the jsonverse package const jsonverse = new Jsonverse("./data"); // Initialize jsonverse with data folder path // Restore data from a backup file into the specified data store using a callback function jsonverse.backupRestore( "exampleData", "backup_20230906120000.json", (error) => { if (error) { console.error("Error restoring data from backup:", error); } else { console.log("Data restored from backup successfully."); } } );

The backupDelete method is used to delete old backups from a specified data store based on retention criteria.

Syntax

jsonverse.backupDelete(dataName, retentionDays);
  • dataName (string): The name or identifier of the data store for which you want to delete old backups.
  • retentionDays (number): The number of days to retain backups. Backups older than this value will be deleted.

Example Usage (With Promises)

const Jsonverse = require("jsonverse"); // Import the jsonverse package const jsonverse = new Jsonverse("./data"); // Initialize jsonverse with data folder path // Delete old backups for the specified data store using promises jsonverse .backupDelete("exampleData", 7) // Retain backups for 7 days .then(() => { console.log("Old backups deleted successfully."); }) .catch((error) => { console.error("Error deleting old backups:", error); });

Example Usage (Without Promises)

const Jsonverse = require("jsonverse"); // Import the jsonverse package const jsonverse = new Jsonverse("./data"); // Initialize jsonverse with data folder path // Delete old backups for the specified data store using a callback function jsonverse.backupDelete("exampleData", 7, (error) => { // Retain backups for 7 days if (error) { console.error("Error deleting old backups:", error); } else { console.log("Old backups deleted successfully."); } });

These backup methods provide essential functionality for data protection
