When replacing the content in bulk on the entire site, which fields need to be backed up before they are changed?
When replacing batch content on the entire site, the fields that need to be backed up are divided into three categories: document data itself (including static files), template files, and independent configurations such as navigation and watermark. If keywords and links in the main text are changed incorrectly, they can still be covered by the recycle bin and revision of each article; there is no ready-made recovery entry after the configuration items are bulk covered, so a snapshot should be frozen before replacement, and the scope of changes should be confirmed after replacement.
Which layers will the full site replacement affect
The station-wide replacement tool rewrite keywords or links in batches, usually covering three layers. The first layer is the document content and metadata, large in quantity and clear in rules, which is the main object for replacement. The second layer is the navigation settings, where navigation names and links are often hit by keyword rules, and the number of navigation entries is small, so once an error occurs, it can be seen throughout the entire station. The third layer is the watermark configuration and other site-level settings, which do not store article data, and are often not prompted when scanned by batch rules.
Make sure to confirm the anchor text separately. The automatic anchor text of the in-site keywords is related to the keywords in the text, but the anchor text rules have not been synchronized checked, which may lead to incorrect page links.
Which objects need to be backed up first
The backup and recovery capability covers data and static files. Before the operation, make sure that this backup includes three contents:
On the database side, the structured data such as documents, categories, and tags must have a complete backup before replacement. In case of errors, restore the entire set. On the file side, static resources such as uploaded images and attachments should also be included in the backup scope, especially when the replacement rules involve resource paths. On the configuration side, it is recommended to manually save a copy of the template files, navigation settings, and watermark management as exports or snapshots, as these areas have a fine granularity of recovery, few in number, and the cost of saving individually is very low.
A convenient judgment standard: any object that is not in the document table or cannot be retrieved from the database after an error is made should be frozen separately before replacement.
How to carry out inspections after replacement?
Do not just check the background records after replacement; inspect from the front-end entry to get closer to what readers see. Suggest following this order: randomly open several articles that were hit, confirm that the semantics after keyword replacement do not destroy the sentence; check each navigation entry one by one to confirm that the names and links point to the correct page; randomly check paragraphs with anchor text links to confirm that the link targets exist and do not point to deleted documents; confirm that the style is not abnormal on pages involving watermarks.
When correcting mistakes, there are two types of handling: data layer errors can be restored from backups or corrected item by item; configuration layer errors should prioritize the use of the frozen snapshot before replacement to restore item by item, narrowing the scope of replacement before execution. The trash can can handle deleted documents by mistake, but cannot handle configurations that have been overwritten, which is why backups need to be made in advance.
Common questions
Question: If a document is corrected, can the trash can save it?Answer: Deleted formal documents will enter the trash can and can be restored; however, the content replaced by replacement is not a deletion action, and there is no version before replacement in the trash can, which needs to rely on backups or item by item correction.
Question: Is it enough to back up the database?Answer: Not enough. The configuration of templates, navigation, watermarks, and others may not be in the document data, and static files are also outside the scope of database backups. It is recommended to freeze data, files, and configurations separately.
Question: The scope of the replacement rule is large, how to reduce the risk?Answer: First, test in a small range, such as limiting a category, and then expand after inspection. Keep a snapshot of the previous step before each expansion, and you can recover the latest one if there is a problem.
