       fsarchiver - filesystem archiver

       fsarchiver  is  a system tool that allows you to save the contents of a
       filesystem to  a	 compressed  archive  file.  The  file-system  can  be
       restored	 on  a	partition  which  has  a  different size and it can be
       restored on a different file-system. Unlike  tar/dar,  FSArchiver  also
       creates	the filesystem when it extracts the data to partitions. Every‐
       thing is checksummed in the archive in order to protect	the  data.  If
       the  archive  is corrupt, you just lose the current file, not the whole

       savefs Save filesystems to archive.

       restfs Restore  filesystems from archive.  This overwrites the existing
	      data on filesystems.  Zero-based index n indicates the  part  of
	      the  archive  to	restore.  Optionally, a filesystem may be con‐
	      verted to fstype.

	      Save directories to archive (similar to a compressed tarball).

	      Restore data from archive which is not based on a filesystem  to

	      Show  information	 about	an  existing archive file and its con‐

       probe  Show list of filesystems detected on the disks.

       -h, --help
	      Show help and information about how to use fsarchiver with exam‐

       -V, --version
	      Show program version and exit.

       -v, --verbose
	      Verbose mode (can be used several times to increase the level of
	      details).	 The details will be printed to the console.

       -o, --overwrite
	      Overwrite the archive if it already exists instead of failing.

       -d, --debug
	      Debug mode (can be used several times to increase the  level  of
	      details).	     The     details	 will	  be	 written    in

       -A, --allow-rw-mounted
	      Allow to save a filesystem which is mounted in read-write	 (live
	      backup).	 By default fsarchiver fails with an error if the par‐
	      tition if mounted in read-write mode which allows	 modifications
	      to  be  done  on the filesystem during the backup. Modifications
	      can drive to inconsistencies in the backup.  Using lvm snapshots
	      is  the  recommended  way	 to make backups since it will provide
	      consistency, but it is only available for filesystems which  are
	      on LVM logical-volumes.

       -a, --allow-no-acl-xattr
	      Allow  to	 run  savefs  when  partition  is  mounted without the
	      acl/xattr options.  By default fsarchiver fails with an error if
	      the  partition  is  mounted  in  such  a	way  that  the ACL and
	      Extended-Attributes are not readable. These attributes would not
	      be  saved	 and  then  such attributes could be lost. If you know
	      what you don't need ACL and Extended-Attributes to be  preserved
	      then it's safe to run fsarchiver with that option.

       -e pattern, --exclude=pattern
	      Exclude  files and directories that match that pattern. The pat‐
	      tern can contains shell asterisks such as * and ?, and the  pat‐
	      tern  may	 be  either  a	simple	file/dir  name	or an absolute
	      file/dir path. You must use quotes around the pattern each  time
	      you  use	wildcards,  else it would be interpreted by the shell.
	      The wildcards must be interpreted by  fsarchiver.	 See  examples
	      below for more details about this option.

       -L label, --label=label
	      Set the label of the archive: it's just a comment about the con‐
	      tents.  It can be used to remember a particular thing about  the
	      archive or the state of the filesystem for instance.

       -z level, --compress=level
	      Valid  compression  levels are between 1 (very fast) and 9 (very
	      good).  The memory requirement increases a  lot  with  the  best
	      compression  levels,  and	 it's multiplied by the number of com‐
	      pression threads (option -j).   Level  9	is  considered	as  an
	      extreme  compression level and requires an huge amount of memory
	      to   run.	   For	 more	details	  please   read	  this	 page:

       -s mbsize, --split=mbsize
	      Split the archive into several files of mbsize megabytes each.

       -j count, --jobs=count
	      Create  more  than  one compression thread. Useful on multi-core
	      CPUs.  By default	 fsarchiver  will  only	 use  one  compression
	      thread  (-j  1) and then only one logical processor will be used
	      for compression.	You should use	that  option  if  you  have  a
	      multi-core  CPU  or more than one physical CPU on your computer.
	      The typical way to use this option is to specify the  number  of
	      logical processors available so that all the processing power is
	      used to compress the archive very quickly. You may also want  to
	      use all the logical processors but one for that task so that the
	      system stays responsive for other applications.

       -c password, --cryptpass=password
	      Encrypt/decrypt data in archive. Password length: 6 to 64 chars.
	      You  can	either provide a real password or a dash ("-c -") with
	      this option if you do not want to provide the  password  in  the
	      command  line  and you want to be prompted for a password in the
	      terminal instead.

   save only one filesystem (/dev/sda1) to an archive:
       fsarchiver savefs /data/myarchive1.fsa /dev/sda1

   save two filesystems (/dev/sda1 and /dev/sdb1) to an archive:
       fsarchiver savefs /data/myarchive2.fsa /dev/sda1 /dev/sdb1

   restore the first filesystem from an archive (first = number 0):
       fsarchiver restfs /data/myarchive2.fsa id=0,dest=/dev/sda1

   restore the second filesystem from an archive (second = number 1):
       fsarchiver restfs /data/myarchive2.fsa id=1,dest=/dev/sdb1

   restore two filesystems from an archive (number 0 and 1):
       fsarchiver	restfs	     /data/arch2.fsa	   id=0,dest=/dev/sda1

   restore a filesystem from an archive and convert it to reiserfs:
       fsarchiver  restfs  /data/myarchive1.fsa id=0,dest=/dev/sda1,mkfs=reis‐

   restore a filesystem from an archive and specify extra mkfs options:
       fsarchiver		  restfs		  /data/myarchive1.fsa
       id=0,dest=/dev/sda1,mkfs=ext4,mkfsopt="-I 256"

   save the contents of /usr/src/linux to an archive (similar to tar):
       fsarchiver savedir /data/linux-sources.fsa /usr/src/linux

   save a /dev/sda1 to an archive split into volumes of 680MB:
       fsarchiver savefs -s 680 /data/myarchive1.fsa /dev/sda1

   save a filesystem and exclude all files/dirs called 'pagefile.*'
       fsarchiver savefs /data/myarchive.fsa /dev/sda1 --exclude='pagefile.*'

   exclude 'share' in both '/usr/share' and '/usr/local/share':
       fsarchiver savefs /data/myarchive.fsa --exclude=share

   absolute exclude valid for '/usr/share' but not '/usr/local/share'
       fsarchiver savefs /data/myarchive.fsa --exclude=/usr/share

   save a filesystem (/dev/sda1) to an encrypted archive:
       fsarchiver savefs -c mypassword /data/myarchive1.fsa /dev/sda1

   extract an archive made of simple files to /tmp/extract:
       fsarchiver restdir /data/linux-sources.fsa /tmp/extract

   show information about an archive and its file systems:
       fsarchiver archinfo /data/myarchive2.fsa

       fsarchiver is still in development, don't use it for critical data yet.
