I tried ports with telnet on my ubuntu and it seemed liked it was open but it didn't work. So I would give it a try :. Pretty sure I've seen something similar.
If you've had a command run as part of a job that runs on that host like a "Client Run Before Job" statement , if that command has paused, or stalls in some way, it breaks bacula even if you restart the agent. If this ends up happening, the "before job" command inherits the listening file descriptor that the agent runs on and keeps it open. If you restart bacula, Windows doesn't ever seem to care that there is already a process that is bound to the listening address bacula should listen on and lets bacula start up.
However all the traffic that you send to bacula is actually being received by the stray command from an old instance of bacula, not bacula itself. Another problem can be that bacula has ran out of maximum connections, but you can just restart the agent in this case to fix that.
I am working on bacula server client back up tool too. I did realise that if your file daemon is newer than the director and storage daemon, that error is thrown. Hope it helps!

Only a single type Backup, Restore, … can be specified for any job. If you want to backup multiple FileSets on the same Client or multiple Clients, you must define a Job for each one.
Note, you define only a single Job to do the Full, Differential, and Incremental backups since the different backup levels are tied together by a unique Job name. Normally, you will have only one Job per Client, but if a client has a really huge number of files more than several million , you might want to split it into to Jobs each with a different FileSet covering only part of the total files.
Multiple Storage daemons are not currently supported for Jobs, so if you do want to use multiple storage daemons, you will need to create a different Job and ensure that for each Job that the combination of Client and FileSet are unique. The Client and FileSet are what Bacula uses to restore a client, so if there are multiple Jobs with the same Client and FileSet or multiple Storage daemons that are used, the restore will not work. This problem can be resolved by defining multiple FileSet definitions the names must be different, but the contents of the FileSets may be the same.
The Job name. This name can be specified on the Run command in the console program to start a job. If the name contains spaces, it must be specified between quotes. It is generally a good idea to give your job the same name as the Client that it will backup.
This permits easy identification of jobs. When the job actually runs, the unique Job Name will consist of the name you specify here followed by the date and time the job was scheduled for execution. This directive is required. Within a particular Job Type, there are also Levels as discussed in the next item. Run a backup Job. Normally you will have at least one Backup job for each client you want to save. Normally, unless you turn off cataloging, most all the important statistics and data concerning files backed up will be placed in the catalog.
Run a restore Job. Normally, you will specify only one Restore job which acts as a sort of prototype that you will modify using the console program in order to perform restores. Although certain basic information from a Restore job is saved in the catalog, it is very minimal compared to the information stored for a Backup job - for example, no File database entries are generated since no Files are saved.
Restore jobs cannot be automatically started by the scheduler as is the case for Backup, Verify and Admin jobs. To restore files, you must use the restore command in the console. Run a verify Job. In general, verify jobs permit you to compare the contents of the catalog to the file system, or to what was backed up.
In addition, to verifying that a tape that was written can be read, you can also use verify as a sort of tripwire intrusion detection. Run an admin Job. An Admin job can be used to periodically run catalog pruning, if you do not want to do it at the end of each Backup Job.
Although an Admin job is recorded in the catalog, very little data is saved. The Level directive specifies the default Job level to be run. The Level is normally overridden by a different value that is specified in the Schedule resource.
This directive is not required, but must be specified either by a Level directive or as an override specified in the Schedule resource. When the Level is set to Full all files in the FileSet whether or not they have changed will be backed up. When the Level is set to Incremental all files specified in the FileSet that have changed since the last successful backup of the the same Job using the same FileSet and Client, will be backed up.
If the Director cannot find a previous valid Full backup then the job will be upgraded into a Full backup. When the Director looks for a valid backup record in the catalog database, it looks for a previous Job with:. If all the above conditions do not hold, the Director will upgrade the Incremental to a Full save. Otherwise, the Incremental backup will be performed as requested. If the file was modified or its attributes changed on or after this start time, it will then be backed up.
For other software, please see their manual. When Bacula does an Incremental backup, all modified files that are still on the system are backed up. However, any file that has been deleted since the last Full backup remains in the Bacula catalog, which means that if between a Full save and the time you do a restore, some files are deleted, those deleted files will also be restored. The deleted files will no longer appear in the catalog after doing another Full save.
As a consequence, those files will probably not be backed up by an Incremental or Differential backup which depend solely on these time stamps. If you move a directory, and wish it to be properly backed up, it is generally preferable to copy it, then delete the original. However, to manage deleted files or directories changes in the catalog during an Incremental backup you can use accurate mode. This is quite memory consuming process.
See Accurate modeaccuratemode for more details. When the Level is set to Differential all files specified in the FileSet that have changed since the last successful Full backup of the same Job will be backed up. If the Director cannot find a valid previous Full backup for the same Job, FileSet, and Client, backup, then the Differential job will be upgraded into a Full backup.
When the Director looks for a valid Full backup record in the catalog database, it looks for a previous Job with:. If all the above conditions do not hold, the Director will upgrade the Differential to a Full save. Otherwise, the Differential backup will be performed as requested.
If the file was modified or its attributes were changed on or after this start time, it will then be backed up. The start time used is displayed after the Since on the Job report.
In rare cases, using the start time of the prior backup may cause some files to be backed up twice, but it ensures that no change is missed. As with the Incremental option, you should ensure that the clocks on your server and client are synchronized or as close as possible to avoid the possibility of a file being skipped.
Note, on versions 1. When Bacula does a Differential backup, all modified files that are still on the system are backed up. However, to remove deleted files from the catalog during a Differential backup is quite a time consuming process and not currently implemented in Bacula. It is, however, a planned future feature. Alternatively, you can move the directory, then use the touch program to update the timestamps. However, to manage deleted files or directories changes in the catalog during an Differential backup you can use accurate mode.
Every once and a while, someone asks why we need Differential backups as long as Incremental backups pickup all changed files. There are possibly many answers to this question, but the one that is the most important for me is that a Differential backup effectively merges all the Incremental and Differential backups since the last Full backup into a single Differential backup. This has two effects: 1. It gives some redundancy since the old backups could be used if the merged backup cannot be read.
More importantly, it reduces the number of Volumes that are needed to do a restore effectively eliminating the need to read all the volumes on which the preceding Incremental and Differential backups since the last Full are done. Since no file data is saved, you might ask why you would want to do this. It turns out to be a very simple and easy way to have a Tripwire like feature using Bacula.
In other words, it allows you to save the state of a set of files defined by the FileSet and later check to see if those files have been modified or deleted and if any new files have been added. This can be used to detect system intrusion.
Typically you would specify a FileSet that contains the set of system files that should not change e. Normally, you run the InitCatalog level verify one time when your system is first setup, and then once again after each modification upgrade to your system.
This compares the results of your InitCatalog with the current state of the files. Compares the current state of the files against the state previously saved during an InitCatalog. Any discrepancies are reported. The items reported are determined by the verify options specified on the Include directive in the specified FileSet see the FileSet resource below for more details.
Typically this command will be run once a day or night to check for any changes to your system files. Please note! If you run two Verify Catalog jobs on the same client at the same time, the results will certainly be incorrect. Note, this is the IP address of the storage server. Since all parts of the Bacula server is running on one host, the address should point to the this server.
Keep scrolling, and you should see that the configuration file is full of sample configuration set by the installation process. Though keep in mind that some of the configurations are pointing to other configurations, some in different configuration files, so we need to make sure that where applicable, the names match up. The client section describes the properties of the client, and can be a network attached client, or describe a client on the same machine where the director is running.
The latter is useful if you want to perform backup of the whole or parts of the backup server. The Catalog section describes how to connect to the database. This is where Bacula will store the information regarding the backup job. The Job section defines the type of backup, what to backup, when to run the backup and where to send messages regarding the backup to mention a few.
It contains several references to other sections, and we will look at those sections further down. The FileSet in this example is very straight forward. Email Address. Excellent article.
