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.

Hans van Kranenburg 59d96420c8 btrbk: add transaction logging to syslog 
Add configuration option transaction_syslog, which can be set to a short
name of a syslog facility, like user or local5. Most of the ones besides
localX do not really make sense, but whatever, let the user decide.

The only logging that is relevant for logging to syslog is the logging
generated inside sub action, so it's easy to hijack all messages in
there and also send them to syslog if needed.

All output is done via print_formatted, which expects a file handle.
So, abuse a file handle to a string to be able to change as less code as
needed for this feature.

Since syslog already adds the timestamps for us, I added a syslog
formatting pattern, which is very similar to tlog, omitting the
timestap.
