Maybe i explained something wrong. I have bacula server on centos
(server), i don't have any deduplication on the bacula server and i
don't need it there. I have windows 2019 server (client), it has it's
own deduplication on it's own volume which is enabled in windows
settings. From this windows volume i need to backup files.
Full backup size before i turn on deduplication (which is windows
deduplication) on windows server (client) was like 200GB, full backup
after i turn on deduplication with same files on the same server was
6.7GB, files count same, when i restoring it, most files is unreadable.
I'm thinking cause bacula makes snapshot of the files when making backup
and it's not working with deduplication on windows server (client), but
maybe i'm wrong.
I just want normal (recoverable) backup from this windows server (which
is 200gb), i don't need any deduplication on my backups.
This is FileSet
FileSet {
Name = "winsrv"
Enable VSS = no
Include {
Options {
compression = GZIP
signature = MD5
aclsupport = yes
}
File = D:/FS/
}
}
this is log from backup:

Hello, i have bacula server 9.6.5 on Centos and i need to backup
folders
from Windows 2019 server client with deduplication on (optimized
files).
Problem if i'm making Full backup, the archive is incomplete
Could you show the job terminate log?
(files
count match, but size is wrong)
I do not understand how you judge that a size is wrong?
Is there any way to tell Bacula server
to ignore deduplication (optimized files) on client or any other way?
I do not understand your statement. Could you elaborate what you want
to achieve and what configuration you use?
Deduplication in Bacula Enterprise Edition is called GED (Global
Endpoint Deduplication) and it is performed on client side (endpoint)
and on storage daemon. You can enable/disable deduplication for a
single FileSet/Include resource.
A deduplication optimized volumes functionality (aligned plugin)
available on Bacula Community requires an external deduplication
solution, hardware or software level to perform the required
computation and management. This solution does not involve a backup
client in any way.
Tried to set "Enable VSS = no" at FileSet but it gives nothing.
VSS is a Microsoft Windows framework and API to manage filesystem
level storage snapshots. It is ignored on non Windows systems and has
nothing to do with deduplication.
I read
manuals but there is only info about how enable deduplication on
server,
not how to backup from such client.
When you enable a deduplication optimized volumes functionality
(aligned plugin) then deduplication could be performed externally
using such solutions like: EMC Data Domain, Quantum DXi or ZFS. No
build in deduplication is available in Bacula Community and aligned
plugin. If you want to enable client side (endpoint) deduplication
then you have to use Bacula Enterprise Edition.
I need to make full backup to restore at another machine where i
don't
have deduplication, so backup chunk store container and optimized
files
separately is not an option.
Bacula is a network backup and restore solution. You do not need to
"copy" saved archives to another machine to do a restore. All you need
is to execute a restore job which will use an existing backup archive
stored on a backup server and not a client.
I need to turn off
FILE_FLAG_OPEN_REPARSE_POINT so i could make normal backup without
using
VSS but i don't understand why option "Enable VSS = no" not working
Bacula should handle reparse points very well. I'm not sure if it
supports all kinds of reparse points available. I think reparse points
are not related to VSS in any way, so switching VSS on or off does not
help.
I do not understand what you want to achieve with this flag, could you
elaborate?
best regards
