Additionally, Bacula compression is performed by the FD, and in many cases the client machines being backed up, laptops, etc., are not very capable. Using filesystem compression moves the compression task to the SD. The same goes for encryption. And good enough is exactly the point. It is possible that a high performance server could encrypt/compress faster than the LTO drive's embedded hardware. Also, consider that, since Bacula performs compression on the FD, it already makes use of multiple cores when backing up multiple clients simultaneously. Certainly, if you backed up enough clients in parallel then the net compression rate would exceed the LTO drive's hardware compression rate. But why bother? The limit is still the raw write speed of the drive/media. As long as the drive's hardware compression/encryption can keep the tape spooling, it is fast enough. If it is not fast enough for the application, then additional LTO drives are needed. -- Try before you buy = See our experts in action!

The _only_ use for compression is on slow WAN links and when writing to disk - and for the latter I'd consider using compressing FSes such as ZFS in preference to using Bacula compression. What about when you are encrypting? You have to do the compression in Bacula as once you've encrypted the data it can no longer be compressed by the drive (eg for LTO LTO4 where the drive cannot encrypt.) Encryption programs generally compress as well in order to increase entropy - so any external compression routines will just make things slower for no gain. As soon as you're doing things which slow down the data flow you have to put up with painfully slow (for me) throughput and you _MUST_ use disk spooling to prevent tape drive shoeshining(*). Multithreading might help but it's generally only available for block-based compression algorithms such as bzip2 (multithreaded decompression isn't available for Pbzip) and that's not going to help much on a stream-based setup such as bacula without major rewrites. Encrypted setups are fine, but bear in mind that 2% of data losses are down to loss of keys - and while a damaged enencrypted backup might be partially recoverable its' highly likely that damage on an encrypted one will result in 100% loss. (*) Anything which results in uncompressed data being presented to the tape drive at a minimum throughput of less than 200MB/s will result in shoeshining (even though the actual tape rate is less than this, if the data is compressaable it needs to feed the drive fast enough to avoid the tape stopping or slowing down. Highly compressable data may require much faster minimum throughputs.) Even slow spool disks are a problem.

Re: [Bacula-users] Re : Restore on windows with VSS stops file daemon service
Hi,
VSS can execute backups of openfiles. I dont think it can make
restores of files that are being used (Not sure, could anyone confirm
?).

Good explanation. I'd strongly support changing the name of the directive in
the configuration file to something like Media Group.
=

=
Yeah I guess it would make sense if Media Group was a list of supported
strings, not a single value.
In this model, sites with multiple devices (tape libraries, disk storage
arrays, etc) could use multiple media types, with each physical device being
assigned a list of media types (in a Media Group) that the device can use.
Furthermore, the device definition in bacula-sd.conf could list properties for
each media type. For example:
Device {
Name = lto5-changer
Media Group = LTO3, LTO4, LTO5
Media Options {
LTO3 = ReadOnly
LTO4 = ReadWrite
LTO5 = ReadWrite
}
}
Device {
Name = lto4-changer
Media Group = LTO2, LTO3, LTO4
Media Options {
LTO2 = ReadOnly
LTO3 = ReadWrite
LTO4 = ReadWrite
}
}
Device {
Name = File
Media Group = localNAS, remoteNAS_for_DR
Media Options {
localNAS = ReadWrite
remoteNAS_for_DR = ReadOnly
}
}

When we moved to an LTO4 library, our solution to that issue was to update
the volume status on all the LTO-2 media to Read-Only (in the bacula
database, but this could have been done with the physical read-only tab
on each tape). Obviously, this would be a problem if we wanted to use
both the LTO3 and LTO4 libraries.
Thanks,
Mark

Re: [Bacula-users] Multi-cores compression
What about when you are encrypting? You have to do the compression in Bacula as once you've encrypted the data it can no longer be compressed by the drive (eg for LTO LTO4 where the drive cannot encrypt.) Encryption programs generally compress as well in order to increase entropy - so any external compression routines will just make things slower for no gain. Thanks Alan, I am specifically addressing the encryption support within Bacula: http://www.bacula.org/en/dev-manual/main/main/Data_Encryption.html Does this pre-compress the data, thus rendering the separate compression redundant? If so, it would be great and probably save us loads of time (about 1 week to back up about 18TB). Cheers Alex -- Try before you buy = See our experts in action!

[Bacula-users] Mysterious Director authentication failures
I'm running Bacula 5.2.5, with Director, catalog and a disk SD on a Solaris 10u9 machine, and a second SD (LTO4 tape) on a Gentoo Linux box. Bacula was compiled using gcc (x86_64-pc-linux-gnu-4.5.3) on the Linux box and with Sun Studio 12.2 opn the Solaris box. Recently I've started experiencing errors in which, after a number of successful connections, Director connection authentication begins repeatedly failing. Example: babylon4:root:/opt/bacula/etc:31 # bconsole Connecting to Director babylon4:9101 Director authorization problem. Most likely the passwords do not agree. If you are using TLS, there may have been a certificate validation error during the TLS handshake. Please see http://www.bacula.org/en/rel-manual/Bacula_Freque_Asked_Questi.html#SECTION00376 for help. From working/babylon4-dir.conmsg: 05-Mar 21:45 babylon4-dir: ERROR in authenticate.c:415 Unable to authenticate console *UserAgent* at client:10.24.32.10:36131. 05-Mar 21:45 babylon4-dir: ERROR in authenticate.c:415 Unable to authenticate console *UserAgent* at client:10.24.32.14:36131. 05-Mar 21:45 babylon4-dir: ERROR in authenticate.c:415 Unable to authenticate console *UserAgent* at client:10.24.32.14:36131. After starting the Director, all connections will succeed initially. All passwords are known good. As a general rule, once one connection attempt fails, all subsequent connection attempts will also fail. Connections are more likely to fail if one or more jobs is running at the time. Has anyone else encountered this or similar behavior? -- Phil Stracchino, CDK#2 DoD#299792458 ICBM: 43.5607, -71.355 ala...@caerllewys.net ala...@metrocast.net p...@co.ordinate.org Renaissance Man, Unix ronin, Perl hacker, SQL wrangler, Free Stater It's not the years, it's the mileage. -- Keep Your Developer Skills Current with LearnDevNow!

It is more a 'Media Group'. every medium in the same group can be requested on every SD that support that 'Media Group'. It doesn't actually have anything to do with the mediums capabilities/size. To add confusion, any given bacula drive can only support one media type. The only way around this problem is to define extra drives for each media type supported (ie, LTO5, LTO4 and (read-only) LTO3). What's wrong with just defining a single media type LTO covering all generations in use? The problem is that you may want to separate your volumes so bacula does not want to try to write to an LTO2 tape on an LTO5 drive. Remember that with LTO drives you can read 2 generations back but only write 1 generation back.
