S3QL User Guide: https://www.rath.org/s3ql-docs/

apt install s3ql

# create ~/.s3ql/authinfo2
[s3c]
storage-url: s3c://polycloud.crowdapis.com/bucket
backend-login: polycloud-key
backend-password: polycloud-secret
fs-passphrase: passphrase

# set the permissions
chmod go-r ~/.s3ql/authinfo2

# initialize the backend
mkfs.s3ql  s3c://polycloud.crowdapis.com/bucket

# mount the bucket
# Note: the default compression is very cpu intensive. --compress none or --compress zlib-6 is recommend
mount.s3ql  --compress zlib-6 s3c://polycloud.crowdapis.com/bucket mount_point/

# Files in mount_point will be stored to polycloud
cp -r backup_files/ mount_point 

# When you are done the file system must be unmounted with
umount.s3ql mount_point
