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
