Title: Corrupted backup files Last modified: October 9, 2018 --- # Corrupted backup files * Resolved [u22](https://wordpress.org/support/users/u22/) * (@u22) * [7 years, 9 months ago](https://wordpress.org/support/topic/corrupted-backup-files/) * I think this is an issue, when I made a backup some files names are changed, example: name-of-file.js to name-of-file_.js for some reason a underscore is added, so when I try to use the backups they are not working. I’m using the last version. - This topic was modified 7 years, 9 months ago by [u22](https://wordpress.org/support/users/u22/).

Also, before the latest 3.6.1, does the issue happens? * [topgun200204](https://wordpress.org/support/users/topgun200204/) * (@topgun200204) * [7 years, 9 months ago](https://wordpress.org/support/topic/corrupted-backup-files/#post-10768396) * I’ve encountered the same problem. I noticed that all my backup files since Oct 8 had the same issue. An underscore was mysteriously added to some .css and some. js files. In my case, the following files were affected: * ``` /theme/theme_name/css/bootstrap.min.css -> file name became bootstrap.min_.css /theme/theme_name/css/fontawesome-all.css -> OK /theme/theme_name/js/bootstrap.min.js -> file name became bootstrap.min_.js /theme/theme_name/js/popper.min_.js -> file name became popper.min_.js ``` * Not sure why the fontawesome-all.css was intact when there other files were affected. I hope this additional underscore was all this issue was about. It will be greatly appreciated if you can advise if there are other issues as I rely on BackWPup on a daily basis and if the issue is more extensive (i.e. affecting database, etc) I will have to stop using it until everything is fixed. * Many thanks! * [topgun200204](https://wordpress.org/support/users/topgun200204/) * (@topgun200204) * [7 years, 9 months ago](https://wordpress.org/support/topic/corrupted-backup-files/#post-10773403) * Hi [@duongcuong96](https://wordpress.org/support/users/duongcuong96/), * Any update on this particular issue?

Or did the issue have other implications that I need to be aware of? * Many thanks! * [Christina Fuchs](https://wordpress.org/support/users/vanvox/) * (@vanvox) * [7 years, 9 months ago](https://wordpress.org/support/topic/corrupted-backup-files/#post-10776034) * [@topgun200204](https://wordpress.org/support/users/topgun200204/) * Info form our devs: The problem affects only the file names by adding an underscore. That happens because files containing more than one dot are treated as to have more than one extention and WordPress adds an underscore before the real extension of the file, because sometimes OS tends to hide the extensions of the file. This is a practice used for security. This is why your files that end with .min.js obtains an underscore after the .min. The issue doesn’t have other implications that you need to be aware of. * Kind regards Christina * [topgun200204](https://wordpress.org/support/users/topgun200204/) * (@topgun200204) * [7 years, 9 months ago](https://wordpress.org/support/topic/corrupted-backup-files/#post-10776273) * Thanks a lot, [@vanvox](https://wordpress.org/support/users/vanvox/)! * Great to know that the issue only affected the file names! * [sean10234](https://wordpress.org/support/users/sean10234/) * (@sean10234) * [7 years, 8 months ago](https://wordpress.org/support/topic/corrupted-backup-files/#post-10787743) * I have been using the plugin for a while without this issue and suddenly now it is changing filenames (by adding underscores to all min.css and min.js files) which effectively makes the backup useless. * [happyAnt](https://wordpress.org/support/users/duongcuong96/) * (@duongcuong96) * [7 years, 8 months ago](https://wordpress.org/support/topic/corrupted-backup-files/#post-10788431) * Hi [@sean10234](https://wordpress.org/support/users/sean10234/), [@all](https://wordpress.org/support/users/all/) The issue is fixed in latest 3.6.2, sorry for any trouble you got. Please update the plugin as soon as possible, thank you very much! * [happyAnt](https://wordpress.org/support/users/duongcuong96/) * (@duongcuong96) * [7 years, 8 months ago](https://wordpress.org/support/topic/corrupted-backup-files/#post-10806879) * [@sean10234](https://wordpress.org/support/users/sean10234/) since we haven’t heard back from you, I’m going to mark it as resolved.
