Very Newbie Linux Full Backup Size

[Richard Rogers]

Hi,

I've just started looking into this app for backing up my Linux and FreeBSD boxes.

I've started by backing up one server, which is a pretty small one.

However, the first full backup is huge (584GB).

The server is an ESXi 6.5 VM with only a 200GB drive assigned.

Obviously there is something I've configured wrong, so any advice gratefully appreciated.

This is what's listed in Bareos:

This is the client's file system:

This the the FileSet:

FileSet {

  Name = "LinuxAll"

  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 = /var/tmp

    File = /.journal

    File = /.fsck

  }

}

JobDef:

  GNU nano 4.8                                                                 /etc/bareos/bareos-dir.d/jobdefs/LinuxJob.conf

JobDefs {

  Name = "LinuxJob"

  Type = Backup

  Level = Incremental

  Client = bareos-fd

  FileSet = "LinuxAll"

  Schedule = "WeeklyCycle"

  Storage = File

  Messages = Standard

  Pool = Incremental

  Priority = 10

  Write Bootstrap = "/var/lib/bareos/%c.bsr"

  Full Backup Pool = Full                  # write Full Backups into "Full" Pool         (#05)

  Differential Backup Pool = Differential  # write Diff Backups into "Differential" Pool (#08)

  Incremental Backup Pool = Incremental    # write Incr Backups into "Incremental" Pool  (#11)

}

Dir Config for Client:

Job {

  Name = "svrwebutil01"

  Client = svrwebutil01-fd

  JobDefs = "LinuxJob"

}

Client {

  Name = svrwebutil01-fd

  Address = svrwebutil01        # the name has to be resolvable through DNS

  Password = "REMOVED"         # password for FileDaemon which has to be the same like the password in the director ressource of the bareos-fd.conf on the backup c>

  File Retention = 30 days            # 30 days

  Job Retention = 6 months            # six months

  AutoPrune = yes                      # Prune expired Jobs/Files

}

Thanks,

Richie

What's the output of "du -sch", executed at the VM's root: "/"

Hi,

This is what I get:

Thanks,

Is it possible that you have a symbolic link that references back up the directory tree.

I have seen problems like this from circular references before.

Hi Richie,

please execute a "df -h" on the server.

Hi,

This is the result of df -h:

@Knauf Steffen: No idea about any sym links that may exist.

Thanks,

Richie

Hi Richie,

i think Andrew Feldmann is right. I only want to ensure that we talk
about a ~200 GB Disk. You only used ~7,1 GB Space, so 550GB is way too
much. Your Confing looks fine.......

Steffen

Hi,

Ok, so that has confirmed the actual size, but why is my backup over 580GB?

What is the next thing to check?

Thanks,

Richie

[Frank Kirschner]

restore the backup to a safe place - don't overwrite the original data - and see, what you have backuped.
maybe like mentioned above symlinks.

Does your file system contain any sparse files (for example,
databases) ?



Best regards,
