Title: Files missing from backups Last modified: June 30, 2026 --- # Files missing from backups * [andyhenderson2](https://wordpress.org/support/users/andyhenderson2/) * (@andyhenderson2) * [5 days, 12 hours ago](https://wordpress.org/support/topic/files-missing-from-backups/) * Our backup file storing programs perform a compare of the file size to a target file size. It raises a warning if a backup file is below target. We have had two warnings in the last week which has revealed that files are being dropped from the backup. * Comparing backups using WinMerge we found: * All except two recent backups are around 70,600KB (the site is a relatively static one). The two that are smaller are missing files: 1. 26/6 backup is missing files from folder /wp-content/uploads/2025/05 2. 30/6 backup is missing files from folder /wp-content/uploads/2023/01 * This is the backup log for 26/6: * ```wp-block-code [INFO] BackWPup 5.7.2; A project of WP Media[INFO] WordPress 6.9.4 on https://cyclehayling.org/[INFO] Log Level: Normal (translated)[INFO] BackWPup job: Files & Database[INFO] Logfile is: backwpup_log_1af57b_2026-06-26_02-01-03.html[INFO] Backup file is located at: /homepages/1/d937068188/htdocs/clickandbuilds/CycleHayling/.../2026-06-26_02-01-03_J3Y5BAOW01_FILE-DBDUMP-WPPLUGIN.zip[2026-06-26 01:01:03 UTC] 1.

Other backups are complete and a consistent size so this is not an access rights issue. * Looking across backups from other sites we also see unexpected drops in backup file sizes. This is obviously a serious concern. * Happy to provide further diagnostics. * Andy Viewing 1 replies (of 1 total) * Plugin Support [Saransh](https://wordpress.org/support/users/saranshwpm/) * (@saranshwpm) * [4 days, 18 hours ago](https://wordpress.org/support/topic/files-missing-from-backups/#post-18952683) * Hello [@andyhenderson2](https://wordpress.org/support/users/andyhenderson2/), Thank you for your message.Our developers have identified the cause of the issue and are already working on a fix.
