Titanium backup history setting ignored Hello 


I am a happy user of Titanium Backup, except for one thing. The maximum backup history is set to 1, a single backup, but over time, the backup folder now contains 88 backups. 
How can I make Titanium Backup only keep the most recent backup? 

Screenshots are attached. 

With kind regards,

Short answer

I'd say everything is working as expected, just your interpretation of the "88 backups" is wrong :)

Explanation

Titanium Backup doesn't make "one huge backup file covering all", but creates one set of backup files per app (usually 2 files: the .apk and the app settings as .tar.gz), plus one set per system data type (call logs, SMS, WiFi APNs, contacts, and such).

So the message "88 backups" is a bit misleading here: you should read that as "88 backup files" (which again would not be correct, as it rather means "88 objects" here; hard to find a proper term for this message: had you set a backup history limit of 2, and 2 of your apps had 2 backups, it would report "90 backups" here).

You can check this out yourself when investigating the backup directory using e.g. a file explorer: Navigate to /storage/emulated/legacy/TitaniumBackup (which should correspond with sdcard/TitaniumBackup and check the files therein. Naming convention is each file starts with the corresponding package name of the app, followed by either a time-stamp or a corresponding HEX string, and ends with either .apk or .tar.gz.
