NAME

BackupPC::Backups::Info - Restrieves info on BackupPC backups.

VERSION

Version 0.1.1

SYNOPSIS

Quick summary of what the module does.

Perhaps a little code snippet.

    use BackupPC::Backups::Info;

    my $bpcinfo = BackupPC::Backups::Info->new();
    ...

METHODS

new

Initiates the object.

One variable is taken and that is the back to the BackupPC pool. By default this is '/var/db/BackupPC' if not specified.

    my $bpcinfo=BackupPC::Backups::Info->new;
    if ( $bpcinfo->error ){
        warn("init failed.... the pool directy does not exist or is not accessible");
    }

get_dir

This returns the top dir for BackupPC.

There is no need for error checking as long as it did not error upon init.

    my $dir=$bpcinfo->get_dir;

get_last

Gets the last line parsed for a for the file.

If the machine has not been parsed yet, it will be and the last entry returned.

Two options are taken.

The first is the machine in question.

The second is perl boolean if it should reread the file even if it already has a last.

The BACKUP HASH for information on the returned hash reference.

    my $lastRef=$bpcinfo->get_last($machine)
    if ( $bpcinfo->error ){
        warn('something happened'.$self->errorstring);
    }

get_pc_dir

This returns the directory which will contain the directories for the hosts setup in BackupPC.

There is no need for error checking as long as it did not error upon init.

    my $dir=$bpcinfo->get_dir;
    if ( $bpcinfo->error ){
        warn('something happened'.$self->errorstring);
    }

get_parsed

This parses the raw backups file and then returns a array of hashes. For a explanation of the hashes, please see BACKUP HASH.

One archment is taken and that is the machine name.

   my @parsed=$bpcinfo->get_parsed($machine);
    if ( $bpcinfo->error ){
        warn('something happened: '.$self->errorstring);
    }

get_raw

This retrieves the law data from a backups file for a machine.

The section on backups file in https://backuppc.github.io/backuppc/BackupPC.html#Storage-layout is suggested reading if you plan on actually using this.

    my $raw=$bpcinfo->get_raw('foo');
    if ($bpcinfo->error){
        warn('something errored');
    }

list_machines

This returns an array of machines backed up.

    my @machines=$bpcinfo->list_machines;
    if ( $bpcinfo->error ){
        warn('something happened: '.$self->errorstring);
    }

list_parsed

This returns a array the machines that have currently been parsed.

As long as no permanent errors are set, this will not error.

    my @parsed=$bpcinfo->list_parsed;

read_in_all

This reads in the backups files for each machine.

Currently this just attempts to read in all via get_parsed and ignores any errors, just proceeding to the next one.

As long as list_machines does not error, this will not error.

    $bpcinfo->read_in_all
    if ( $bpcinfo->error ){
        warn('something happened: '.$self->errorstring);
    }

BACKUP HASH

Based on __TOPDIR__/pc/$host/backup from https://backuppc.github.io/backuppc/BackupPC.html#Storage-layout.

num

The backup number for the current hash.

type

Either 'incr' or 'full'.

startTime

The unix start time of the backup.

endTime

The unix end time of the backup.

nFiles

Number of files backed up.

size

Total file size backed up.

nFilesExist

Number of files already in the pool.

sizeExist

Total size of files that were already in the pool.

nFilesNew

Number of new files not already in the pool.

sizeNew

Total size of files not in the pool.

xferErrs

Number of warnings/errors from the backup method.

xferBadFile

Number of errors from the backup method in regards to bad files.

xferBadShare

Number of errors from smbclient that were bad share errors.

tarErrs

Number of errors from BackupPC_tarExtract.

compress

The compression level used on this backup. Zero means no compression.

Please note that while BackupPC may leave this field blank if none is used, this module will check for a blank value and set it to zero.

sizeExistComp

Total compressed size of files that already existed in the pool.

sizeNewComp

Total compressed size of new files in the pool.

noFill

et if this backup has not been filled in with the most recent previous filled or full backup. See $Conf{IncrFill} in the BackupPC docs.

fillFromNum

If filled, this is the backup it was filled from.

mangle

Set if this backup has mangled file names and attributes. Always true for backups in v1.4.0 and above. False for all backups prior to v1.4.0.

xferMethod

The value of $Conf{XferMethod} when this dump was done.

level

ERROR FLAGS
