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 
implemented directly in btrfs_subvolume_delete()
 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.

Axel Burri 961f96833a btrbk: use "dd" for raw target output, with configurable block size (raw_target_block_size) 
We use "dd" instead of shell redirections, as it is common to have
special filesystems (like NFS, SMB, FUSE) mounted on the raw target
path. By using "dd" we make sure to write in reasonably large blocks
(default=128K), which is not always the case when using redirections
(e.g. "gpg > outfile" writes in 8K blocks).

Another approach would be to always pipe through "cat", which uses
st_blksize from fstat(2) (with a minimum of 128K) to determine the
block size.
