When operating systems such as websites and servers, data “backup” is an essential element.<\/p>\n

However, in actual practice, a certain number of companies still do not take backups at all. They are in a state of “understanding the importance of backups, but postponing action.”<\/p>\n

This article focuses on the design of the backup process and organizes and explains the concept of backups.<\/p>\n

Many Companies Do Not Backup<\/h2>\n

\"\"<\/p>\n

There are certainly companies that do not back up their data. Moreover, this is not only an issue for some large enterprises; it is a trend widely seen among small and medium-sized businesses and small-scale operators.<\/p>\n

For example, in small and medium-sized businesses, shortages of personnel, budget, and time have become obvious, so the priority of backup measures is extremely low. This is a realistic issue faced by many companies.<\/p>\n\n\n\n\n\n\n\n\n
Common Voices<\/span><\/td>\nReality<\/span><\/td>\n<\/tr>\n
Work is busy, and there are not enough people, budget, or time<\/td>\nThe loss is far greater when data disappears<\/td>\n<\/tr>\n
We do not really know how to do it<\/td>\nIt appears to require specialized knowledge and skills<\/td>\n<\/tr>\n
We are a small company, so we will not be targeted<\/td>\nCyber attackers target companies of all sizes<\/td>\n<\/tr>\n
It is in the cloud, so it is fine<\/td>\nCloud providers do not protect “the contractor’s own data management”<\/td>\n<\/tr>\n
We intend to do it someday<\/td>\nNo matter how much time passes, it is never started<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Backup Is the Foundation of “BCP”<\/h2>\n

\"\"<\/p>\n

BCP (Business Continuity Plan) is a plan for minimizing damage to a company and restarting business at an early stage when a disaster, failure, cyberattack, or similar event occurs.<\/p>\n

And “backup” is the foundation of that BCP. No matter how detailed a BCP is formulated, if the essential data is lost, business cannot be restarted.<\/p>\n

In other words, backup is the foundation of “BCP,” and thinking about BCP also means thinking about backup.<\/p>\n\n\n\n\n\n\n\n\n

Preparing for Basic Backups<\/h2>\n

\"\"<\/p>\n

Companies that have not yet implemented backup measures should proceed with preparing the following items.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n
Item<\/span><\/td>\nOverview<\/span><\/td>\n<\/tr>\n
Take inventory of the data to be protected<\/td>\nOrganize customer lists, accounting data, contracts, system account permissions, etc<\/td>\n<\/tr>\n
Replicate and store the data<\/td>\nDatabases such as MySQL are dumped using mysqldump<\/span> and stored in network-isolated cloud storage or similar locations<\/td>\n<\/tr>\n
Capture an image of the entire system<\/td>\nTake an image backup that includes settings such as the server OS, so that the system can be restored quickly in the event of a failure<\/td>\n<\/tr>\n
Set up a mechanism to acquire data automatically<\/td>\nConfigure data synchronization or automatic backup functions<\/td>\n<\/tr>\n
Distribute replicated data across different environments<\/td>\nDistribute it physically and logically, such as across different regions, different clouds, or on-premises environments<\/td>\n<\/tr>\n
Separate account permissions<\/td>\nSeparate the accounts for the production environment and the backup environment<\/td>\n<\/tr>\n
Make the data impossible to delete<\/td>\nUse immutable storage (which cannot be deleted or updated) and configure deletion protection<\/td>\n<\/tr>\n
Check whether the data can be restored<\/td>\nCheck whether the data is synchronized and has not been deleted, and regularly verify data restoration<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Point 1: Scope of Data to Be Backed Up<\/h3>\n

For example, on websites built with a CMS such as WordPress, it is standard practice to back up not only the site files but also the database.<\/p>\n

This is because without that database, you cannot restore data such as the articles and settings within the site.<\/p>\n

If your environment uses a MySQL database, obtain a “dump file” of the database in advance using a command such as mysqldump<\/span>.<\/p>\n

Point 2: Distributed Storage of Data Across Separate Environments<\/h3>\n

In recent years, the idea of “distributing replicated data across separate environments and applying dual or triple backups”<\/strong> has become important.<\/p>\n

For example, if backups are stored in “only one location” on the same server or cloud environment, then if that account is compromised, a failure occurs, or a misconfiguration happens, the backups will be lost along with the production data.<\/p>\n

There are also cases where a cyberattacker deletes all data, including the backups.<\/p>\n

Although this requires budget and effort, having “data that also exists in another location” makes it possible to cope with unexpected contingencies.<\/p>\n

Point 3: Immutable Data Protection<\/h3>\n

Cloud services such as Alibaba Cloud and AWS provide an “immutable (WORM: Write Once, Read Many)” mechanism that protects objects (data) from deletion and overwriting for a certain period.<\/p>\n

In these cloud services, by setting a retention period and locking it at the bucket level, objects cannot be deleted or overwritten during that period.<\/p>\n

Note that while this provides strong security, careless operation that sets an excessively long retention period can make the data truly impossible to delete, so caution is required.<\/p>\n\n\n\n\n
Alibaba Cloud\uff08Aliyun\uff09OSS BucketWorm<\/span><\/td>\nA default retention period can be set on a bucket, and compliance mode provides even stronger protection<\/td>\n<\/tr>\n
AWS S3 Object Lock<\/span><\/td>\nThe policy is locked at the bucket level, and once locked, the retention period cannot be deleted or shortened<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Summary<\/h2>\n

System “backup” is an indispensable element for continuing to use websites and servers safely and securely.<\/p>\n

Don’t forget to perform regular backups and verification, and promote dual or triple data storage in separate environments to prepare for unexpected contingencies.<\/p>\n
