Installation and Upgrade
aws-s3-glacier-restore is developed in Python and uses pip.
The easiest way to install/upgrade s3select is to use
pip in a
$ pip install -U aws-s3-glacier-restore
or, if you are not installing in a
virtualenv, to install/upgrade globally:
$ sudo pip install -U aws-s3-glacier-restore
or for your user:

aws-s3-glacier-restore uses the same authentication and endpoint configuration as aws-cli. If aws command is working on your machine, there is no need for any additional configuration.
First get some help:
$ aws-s3-glacier-restore -h usage: aws-s3-glacier-restore [-h] [-p PREFIX] [-i INPUT_FILE] [-d DAYS_TO_KEEP] [-D DESTINATION_BUCKET] [-t THREADS] [-s] [--profile PROFILE] Utility script to restore files on AWS S3 that have GLACIER storage class optional arguments: -h, --help show this help message and exit -p PREFIX, --prefix PREFIX S3 prefix URL to restore -i INPUT_FILE, --input_file INPUT_FILE Input file containing all s3 paths to restore -d DAYS_TO_KEEP, --days_to_keep DAYS_TO_KEEP How many days to keep restored files -D DESTINATION_BUCKET, --destination_bucket DESTINATION_BUCKET Restore to this bucket instead of to original bucket while preserving same path structure as in original bucket. This is useful if you don't know for how long you'll need restored files. Once you don't need them you can delete them from destination bucket. -t THREADS, --threads THREADS Number of threads to use. Default=40 -s, --status_print Just print status of files and how many of them are in glacier and how many of them are restored already --profile PROFILE Use a specific AWS profile from your credential file.
Then full run might look like this:
$ aws-s3-glacier-restore -p s3://test-restore-bucket/backup2/image_1503789115/part-r-0003 -d 2 Getting a listing of the files to restore...

Parameter --days_to_keep (-d) specifies how long files will be accessible as regular files over S3. In case you have finished with files earlier than expected or want to extend the amount of days they are kept available, you can run the same command, but this time with modified "-d" parameter. If you specify "-d 1" this will signal that files should be archived back as soon as possible (usually happens within one day):
$ aws-s3-glacier-restore -p s3://test-restore-bucket/backup2/image_1503789115/part-r-0003 -d 0
If you want to check restore status of files you can use -s switch:
$ aws-s3-glacier-restore -p s3://test-restore-bucket/archives/cars/GlacierImageArchive_2017_10-00000001-r-0009 -s Getting a listing of the files...
