Backup Size for Linux Reported Incorrectly

Hi. I’m new to UrBackup and really like it. Unfortunately I have one issue I can’t figure out and I have been unable to find any topics on this.

I have a small Linux server running CentOS 7. The system uses a single 50GB disk of which 8.7GB are used. I’m excluding information about swap size, /boot/ etc. I am doing file backups only. Each full backup shows as a little over 58GB and incrementals are 51GB.

I have checked the following:

  • urbackup logs (client)
  • the size of the backups stored on the server
  • done a df -h on the client
  • done a du -lh on both client and server (where the client backups are stored)

Every place I look, including the amount of time is takes for the backup to perform on my hardware, shows that the actual data transfer matches what I would expect, about 9GB on Full backup. But the webclient shows much more.

4 backups. 3 Full, 1 incremental - Total Size: about 213GB

Server: du -h on storage directory for client

Server: du -lh on storage directory for client

Client: df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/centos-root 50G 8.6G 42G 18% /
devtmpfs 3.9G 0 3.9G 0% /dev
tmpfs 3.9G 0 3.9G 0% /dev/shm
tmpfs 3.9G 401M 3.5G 11% /run
tmpfs 3.9G 0 3.9G 0% /sys/fs/cgroup
/dev/sda1 497M 302M 195M 61% /boot
tmpfs 783M 0 783M 0% /run/user/996
tmpfs 783M 0 783M 0% /run/user/0
tmpfs 783M 0 783M 0% /run/user/1000

Server is on a basic debian 9 linux system. No btrfs or zfs. no dedup. This is also the only Linux client I’ve backed up so far.

Client backup paths are:
Include: /
Exclude: /run/;/sys/;/dev/;/proc/

This isn’t really a big problem as the discrepancy seems to only be in the Web client reporting. It’s possibly something very simple I’m missing. Any help would be appreciated. Also,not sure if it matters but the root volume is an LVM vol.
