NAME
Net::Amazon::Glacier - An implementation of the Amazon Glacier RESTful API.
VERSION
Version 0.13
SYNOPSIS
This module implements the Amazon Glacier RESTful API, version 2012-06-01 (current at writing). It can be used to manage Glacier vaults and upload archives to them. Amazon Glacier is Amazon's long-term storage service.
Perhaps a little code snippet.
use Net::Amazon::Glacier;
my $glacier = Net::Amazon::Glacier->new(
'eu-west-1',
'AKIMYACCOUNTID',
'MYSECRET',
);
my $vault = 'a_vault';
my @vaults = $glacier->list_vaults();
if ( $glacier->create_vault( $vault ) ) {
if ( my $archive_id = $glacier->upload_archive( './archive.7z' ) ) {
my $job_id = $glacier->inititate_job( $vault, $archive_id );
# Jobs generally take about 4 hours to complete
my $job_description = $glacier->describe_job( $vault, $job_id );
# For a better way to wait for completion, see
# http://docs.aws.amazon.com/amazonglacier/latest/dev/api-initiate-job-post.html
while ( $job_description->{'StatusCode'} ne 'Succeeded' ) {
sleep 15 * 60 * 60;
$job_description = $glacier->describe_job( $vault, $job_id );
}
my $archive_bytes = $glacier->get_job_output( $vault, $job_id );
# Jobs live as completed jobs for "a period", according to
# http://docs.aws.amazon.com/amazonglacier/latest/dev/api-jobs-get.html
my @jobs = $glacier->list_jobs( $vault );
# As of 2013-02-09 jobs are blindly created even if a job for the same archive_id and Range exists.
# Keep $archive_ids, reuse the expensive job resource, and remember 4 hours.
foreach my $job ( @jobs ) {
next unless $job->{ArchiveId} eq $archive_id;
my $archive_bytes = $glacier->get_job_output( $vault, $job_id );
}
}
}The functions are intended to closely reflect Amazon's Glacier API. Please see Amazon's API reference for documentation of the functions: http://docs.amazonwebservices.com/amazonglacier/latest/dev/amazon-glacier-api.html.
CONSTRUCTOR
new( $region, $access_key_id, $secret )
VAULT OPERATORS
create_vault( $vault_name )
Creates a vault with the specified name. Returns true on success, false on failure. Create Vault (PUT vault)
delete_vault( $vault_name )
Deletes the specified vault. Returns true on success, false on failure. Delete Vault (DELETE vault)
describe_vault( $vault_name )
Fetches information about the specified vault. Returns a hash reference with the keys described by http://docs.amazonwebservices.com/amazonglacier/latest/dev/api-vault-get.html. Returns false on failure. Describe Vault (GET vault)
list_vaults
Lists the vaults. Returns an array with all vaults. Amazon Glacier List Vaults (GET vaults).
A call to list_vaults can result in many calls to the the Amazon API at a rate of 1 per 1,000 vaults in existence. Calls to List Vaults in the API are free.
set_vault_notifications( $vault_name, $sns_topic, $events )
Sets vault notifications for a given vault. An SNS Topic to send notifications to must be provided. The SNS Topic must grant permission to the vault to be allowed to publish notifications to the topic. An array ref to a list of events must be provided. Valid events are ArchiveRetrievalCompleted and InventoryRetrievalCompleted upon job completion may also be supplied. Return true on success, false otherwise. Set Vault Notification Configuration (PUT notification-configuration).
get_vault_notifications( $vault_name )
Gets vault notifications status for a given vault. Return false on failure or a hash with an 'SNSTopic' and and array of 'Events' on success. Get Vault Notifications (GET notification-configuration).
delete_vault_notifications( $vault_name )
Deletes vault notifications for a given vault. Return true on success, false otherwise. Delete Vault Notifications (DELETE notification-configuration).
ARCHIVE OPERATIONS
upload_archive( $vault_name, $archive_path, [ $description ] )
Uploads an archive to the specified vault. $archive_path is the local path to any file smaller than 4GB. For larger files, see multi-part upload. An archive description of up to 1024 printable ASCII characters can be supplied. Returns the Amazon-generated archive ID on success, or false on failure. Upload Archive (POST archive)
delete_archive( $vault_name, $archive_id )
Issues a request to delete a file from Glacier. $archive_id is the ID you received either when you uploaded the file originally or from an inventory. Delete Archive (DELETE archive)
JOB OPERATIONS
initiate_archive_retrieval( $vault_name, $archive_id, [ $description, $sns_topic ] )
Initiates an archive retrieval job. $archive_id is an ID previously retrieved from Amazon Glacier. A job description of up to 1,024 printable ASCII characters may be supplied. An SNS Topic to send notifications to upon job completion may also be supplied. Initiate a Job (POST jobs).
initiate_inventory_retrieval( $vault_name, [ $format, $description, $sns_topic ] )
Initiates an inventory retrieval job. $format is either CSV or JSON (default). A job description of up to 1,024 printable ASCII characters may be supplied. An SNS Topic to send notifications to upon job completion may also be supplied. Initiate a Job (POST jobs).
initiate_job( ( $vault_name, $archive_id, [ $description, $sns_topic ] )
Effectively calls initiate_inventory_retrieval. Exists for the sole purpose or implementing the Amazon Glacier Developer Guide (API Version 2012-06-01) nomenclature. Initiate a Job (POST jobs).
describe_job( $vault_name, $job_id )
Retrieves a hashref with information about the requested JobID. Amazon Glacier Describe Job (GET JobID).
get_job_output( $vault_name, $job_id, [ $range ] )
Retrieves the output of a job, returns a binary blob. Optional range parameter is passed as an HTTP header. Amazon Glacier Get Job Output (GET output).
list_jobs( $vault_name )
Return an array with information about all recently completed jobs for the specified vault. Amazon Glacier List Jobs (GET jobs).
A call to list_jobs can result in many calls to the the Amazon API at a rate of 1 per 1,000 recently completed job in existence. Calls to List Jobs in the API are free.
NOT IMPLEMENTED
The following parts of Amazon's API have not yet been implemented. This is mainly because the author hasn't had a use for them yet. If you do implement them, feel free to send a patch.
Multipart upload operations
