   4 Subject: [PATCH v5 0/6] Efficient VM backup for qemu
   5
   6 This series provides a way to efficiently backup VMs.
   7
   8 * Backup to a single archive file
   9 * Backup contain all data to restore VM (full backup)
  10 * Do not depend on storage type or image format
  11 * Avoid use of temporary storage
  12 * store sparse images efficiently
  13
  14 The file docs/backup.txt contains more details.
  15
  16 Changes since v1:
  17
  18 * fix spelling errors
  19 * move BackupInfo from BDS to BackupBlockJob
  20 * introduce BackupDriver to allow more than one backup format
  21 * vma: add suport to store vmstate (size is not known in advance)
  22 * add ability to store VM state
  23
  24 Changes since v2:
  25
  26 * BackupDriver: remove cancel_cb
  27 * use enum for BackupFormat
  28 * vma: use bdrv_open instead of bdrv_file_open
  29 * vma: fix aio, use O_DIRECT
  30 * backup one drive after another (try to avoid high load)
  31
  32 Changes since v3:
  33
  34 * move reviewer info from commit messages to cover-letter
  35 * remove 'RFC' from log headers and file names
  36 * removed comment about slow qcow2 snapshot bug
  37 * fix spelling errors
  38 * fixed copyright
  39 * change 'backupfile' parameter name to 'backup-file'
  40 * change 'config-filename' parameter name to 'config-file'
  41 * add documentation for 'devlist' parameter.
  42 * rename backup_cancel to backup-cancel
  43
  44 Changes since v4:
  45
  46 * vma create: write verbose output to stderr (not stdout)
  47 * backup.c: use rwlock instead of sleep, remove backup_in_progress_count
  48 * BackupDriver: remove '_cb' suffix
  49 * include cleanups suggested by Stefan
  50 * use CHAR_BIT instead of magic number '8'
  51 * implemented bdrv_co_is_allocated_above() - disabled for now because
  52   it actually slows down backup speed by 15%
  53 * extend regression tests to test unallocated regions
  54
