Mystcraft worlds are not being backed up!

Check the backup configuration.
There are simple rules on what is backed up and what not.

# Configuration file

Backup {
    # Backup all worlds by default
    B:backup_default=false

    # Automatic backup interval in minutes (0 to disable)
    I:backup_interval=60

    # Always backup worlds when loaded (server starts)
    B:backup_on_load=true

    # Always backup when a world is unloaded
    B:backup_on_unload=true

    # Folder to store the backups in. Can be anywhere writable in the file system.
    S:base_folder=.\ForgeEssentials\Backups

    # Define file patterns (regex) that should be excluded from each backup
    S:exclude_patterns <
        DIM-?\d+
        FEMultiworld
        FEData_backup
        DimensionalDoors
     >

    # Keep at least this amount of last backups
    I:keep_backups=1

    # Keep at least one daily backup for this last number of last days
    I:keep_daily_backups=1

    # Keep at least one weekly backup for this last number of weeks
    I:keep_weekly_backups=1

    #########################################################################
    # Worlds
    #-----------------------------------------------------------------------#
    # Add world configurations in the format "B:1=true"
    #########################################################################

    Worlds {
        B:0=true
    }
}

@Nicba1010 Let us know if this solved your problem

Yea, I will agree with you. FE's backup solution isn't the best backup solution. FE design is to simply provide a backup option but FE has never been a dedicated backup mod.

hi, sorry for thread necromancy. I wass looking for explanation of configuration file and I've found nothing. Some parts of config file is a little bit cryptic:

• what does it mean "Worlds B:0=true" ?

• world "world" isn't included in backup, only world inside folder DIM1, DIM2, DIM-1, etc. World itself (i.e. folder "world") is missing.

• to be clear: backup means backuping of SAVED chunks. So its desirable to make some autosaving of world, right?

Normally there is a backup for world... So perhaps that is a bug, We don't reopen closed issues that have been closed for years so, I would recommend creating an issue following our issue format and rules including as much details as possible. Also, I agree that the config file is cryptic... I have no idea what B:0=true means. I assume it means Boolean '0' = true but I am not sure.

As a note, that config is done in the Forge Config format. S = String, B = Boolean, I = int

 S:exclude_patterns <

>

is an String array

Worlds {

}
is a sub group

I got it from other config: "B:0=true" - "0" is dimension number (i.e. 0=overworld, -1=nether, etc. So "B:0=true" means "backup overworld - yes"). That solved my first and second problem (see above).

The third problem: backup backups all chunks always.

Finally I decided to move to Aroma Backup. Much much much better solution.

This issue could be closed... thanks.
