When I do a full backup of this system, the backup take took more than 5 hours, wrote 763GB on 9 volumes as you can see in the report below.

I am having this behaviour with my other centos 7 systems and it is filling up the disk storage, Is this normal behaviour?

Steps To ReproduceI have tried on other centos 7 systems and get the same results

Sparse files ? without sparse file setting in fileset
Backing up the data that you backup e.g. forgot to exclude the backup area ?
Not backing up any device files etc. e.g. the normal fileset work fine for

If its backing up that data amount its there we do not make up anything just
walk the filesystem open the files and backup the data.

Try the estimate command on the client with the same fileset and check what
included is what you expect to be part of the backup.

Thousands of backups are made every day so this must be a local config problem.

Here is the estimate. Seems to match the number of bytes copied. I cant understand how a disk of 65GB would hold 763.4 GB of data...thats puzzling

Using Catalog "MyCatalog"
Connecting to Client freeipa01-fd at freeipa01:9102
2000 OK estimate files=87,679 bytes=763,406,448,298

 FD Bytes Written: 763,405,009,097 (763.4 GB)

Found the problem, sparse files... but setting sparse to yes did not fix it either, had to exclude /var/log/lastlog

[root@freeipa01 log]# du -h /var/log/lastlog
60K /var/log/lastlog

[root@freeipa01 log]# du -h --apparent-size lastlog
354G lastlog
