Axel Burri e9a517f161 btrbk: add options "{snapshot,target,archive}_qgroup_destroy": destroy qgroups whenever a subvolume is deleted 
Btrfs does not destroy qgroups when subvolumes are deleted (see
https://bugzilla.kernel.org/show_bug.cgi?id=91751). As a workaround
for this, btrbk can be configured to always destroy the corresponding
default qgroup "0/<subvol-id>" whenever a subvolume (snapshot, backup
or archive) is deleted.

Added configuration options:
 - snapshot_qgroup_destroy
 - target_qgroup_destroy
 - archive_qgroup_destroy

Axel Burri 422d52c063 btrbk: add key derivation for encrypted raw targets using external backend 2017-09-28 14:17:00 +02:00
Axel Burri de7628ac7c btrbk: add openssl_enc encryption for raw targets; add system_urandom() 
Example:

Manually create a key:

    # KEYFILE=/some/secure/place/btrbk.key
    # dd if=/dev/urandom bs=1 count=32 | od -x -A n | tr -d "[:space:]" > $KEYFILE

btrbk.conf:

    volume /mnt/btr_pool
      incremental no
      raw_target_encrypt  openssl_enc
      openssl_ciphername  aes-256-cbc
      openssl_iv_size     16  # NOTE: set to "no" if no IV is needed by the selected cipher
      openssl_keyfile     /some/secure/place/btrbk.key

      subvolume home
        target raw ssh://cloud.example.com/backup

Axel Burri e804930b5e btrbk: allow deletion of non-incremental raw targets

 2017-09-28 14:17:00 +02:00
Axel Burri cd8d7e3a0a btrbk: use sidecar file "*.info" instead of encoding uuids into filename for raw targets 
pros:

 - better forward compatibility, e.g. symmetrical encryption
 - better readability of files

cons:

 - two files per backup

Axel Burri 88aa8c1fea btrbk: remove "duration" column from transaction_log/transaction_syslog 
The "duration" column in the transaction log has proven to be
confusing to some users, especially on errors (e.g. "send-receive
ERROR 27" in issue #177). As it's not really necessary (duration can
be computed from the corresponding "starting" log entry), it's now
being dropped.
