Hi all,

I switch backups into bareos 21.0.0 and after first backup my systems I have problem with size of some jobs.

My infra inhalt many small el8 linux systems. Some is backed up in cca 10min and backup OS files take about 10GB.

But some of the backup job takes about 200GB. Is there any way howto check what take the backup capacity? All systems is almost identicaly, backup succesufully, but there is big difference in backup size.

How does your file set look like? I guess, you include /proc/kcore or something similar in your backup.

I check this many times, but It seems OK...

FileSet {
Name = "LinuxOs"
Description = "Backup all regular filesystems, determined by filesystem type."
Include {
Options {
Signature = MD5 # calculate md5 checksum per file
One FS = No # change into other filessytems
FS Type = btrfs
FS Type = ext2 # filesystems of given types will be backed up
FS Type = ext3 # others will be ignored
FS Type = ext4
FS Type = reiserfs
FS Type = jfs
FS Type = xfs
FS Type = zfs
}
File = /
}
# Things that usually have to be excluded
# You have to exclude /var/lib/bareos/storage
# on your bareos server
Exclude {
File = /var/lib/bareos
File = /var/lib/bareos/storage
File = /proc
File = /tmp
File = /dev
File = /var/tmp
File = /.journal
File = /.fsck
File = /srv
File = /var/www
File = /misc
File = /mnt
File = /proc
File = /run
File = /sys
}
}

This looks good. Please also show job log of job 245. There we can validate, this file set is really used.

Regards,

Andreas

Hi all,

Problem is file /var/log/lastlog which expand to very large file, but without usage storage space.

Solution is here https://www.cyberciti.biz/faq/howto-display-clear-last-login-information/

But I expect that helps me select query from database, but I can't find size information in file and directory tables. So I had to list files to restore or export backup, so it is action with long duration.
