I'm thinking the spare file support isn't working so good. I set "sparse
= yes" in the fileset options. Then told it to just backup
/var/log/lastlog. Maybe I did something wrong with my configuration?
FileSet {
Name = "ottertail lastlog"
Include {
Options {
signature = MD5
compression = lz4
checkfilechanges = yes
aclsupport = yes
xattrsupport = yes
noatime = yes
sparse = yes
}
File = /var/log/lastlog
}
#
# If you backup the root directory, the following two excluded
# files can be useful
#
Exclude {
File = /proc
File = /tmp
File = /.journal
File = /.fsck
File = /var/cache
File = /var/tmp
File = /dev
File = /mnt
File = /var/lib/bareos
# skip database directories, these need to be backed up other ways
File = /var/lib/pgsql/data
File = /var/lib/mysql
File = /var/lib/ldap
File = /var/lib/kerberos/krb5kdc/principal
}
}
>ls -lh /var/log/lastlog ; du -h /var/log/lastlog
-rw-rw-r-- 1 root utmp 499G Jan 10 09:18 /var/log/lastlog
4.0K /var/log/lastlog
The job reported:
FD Bytes Written: 2,571,221,216 (2.571 GB)
SD Bytes Written: 2,571,221,897 (2.571 GB)
That suggests to me that the file wasn't recognized as sparse.
I tried a restore and the resulting file shows
du -h test-restore/var/log/lastlog; ls -lh test-restore/var/log/lastlog
499G test-restore/var/log/lastlog
-rw-rw-r-- 1 root utmp 499G Jan 10 08:08 test-restore/var/log/lastlog
So it definitely was not restored as a sparse file.
