has this issue been solved? I am having exactly this problem - incremental backups size = original backup size. It is consuming much space on backup server. The initial full size backup of thunderbird folder is 17GB (terminal). Each incremental directory has the same ± 16/17GB. Is there a way to get incremental backup only new or modified files? UrBackup Server v220.127.116.11 on Debian 10, filesystem ext4. Client is Windows 10 pro, thunderbird mail client, imap. I am backing up path “c:\Users\user\AppData\Roaming\Thunderbird\Profiles”. Client version is ± 1 month old, can’t verify now as client is out on business. Zip file with xlsx data attached. urbackup.zip (6.2 kB)
Thank you much for any help.
