fsarchiver 0.4.4 (Default branch)
fsarchiver is a system tool that allows you tosave the contents of a filesystem to a compressed archive file. The filesystem can be restored on a partition that has a different size, and it canbe restored on a different filesystem. Unliketar/dar, fsarchiver also creates the filesystemwhen it extracts the data to partitions.Everything is checksummed in the archive in orderto protect the data. If the archive is corrupt,you just lose the current file, not the wholearchive.License: GNU General Public License v2Changes:
The compression ratio has been optimized for filesystems with many small files. Instead of compressing the data of each file in a separate block, multiple small files now share the same data block, which provides a better compression ratio. A bug regarding the unmount which is done at the end of the operation was fixed. The "-a" option was added, which allows you to ignore the check for the acl and user_xattr mount options when the user is doing a backup of a filesystem which is already mounted.Image

DEBUGREISERFS(8)                                              System Manager's Manual                                             DEBUGREISERFS(8)

NAME

       debugreiserfs - The debugging tool for the ReiserFS filesystem.

SYNOPSIS

       debugreiserfs [ -dDJmoqpuSV ] [ -j device ] [ -B file ] [ -1 N ]

       device

DESCRIPTION

       debugreiserfs sometimes helps to solve problems with reiserfs filesystems.  When run without options it prints the super block of the Reis-
       erFS filesystem found on the device.

       device is the special file corresponding to the device (e.g /dev/hdXX for an IDE disk partition or /dev/sdXX for a SCSI disk partition).

OPTIONS

       -j device
              prints the contents of the journal. The option -p allows it to pack the journal with other metadata into the archive.

       -J     prints the journal header.

       -d     prints the formatted nodes of the internal tree of the filesystem.

       -D     prints the formatted nodes of all used blocks of the filesystem.

       -m     prints the contents of the bitmap (slightly useful).

       -o     prints the objectid map (slightly useful).

       -B file
              takes the list of bad blocks stored in the internal ReiserFS tree and translates it into an ascii  list  written  to  the  specified
              file.

       -1 blocknumber
              prints the specified block of the filesystem.

       -p     extracts the filesystem's metadata with debugreiserfs -p /dev/xxx | gzip -c > xxx.gz. None of your data are packed unless a filesys-
              tem corruption presents when the whole block having this corruption is packed. You send us the output, and we use  it  to  create  a
              filesystem  with  the same strucure as yours using debugreiserfs -u.  When the data file is not too large, this usually allows us to
              quickly reproduce and debug the problem.

       -u     builds the ReiserFS filesystem image with gunzip -c xxx.gz | debugreiserfs -u /dev/image of  the  previously  packed  metadata  with
              debugreiserfs  -p.  The result image is not the same as the original filesystem, because mostly only metadata were packed with debu-
              greiserfs -p, but the filesystem structure is completely recreated.

       -S     When -S is not specified -p deals with blocks marked used in the filesystem bitmap only. With this  option  set  debugreiserfs  will
              work with the entire device.

       -q     When -p is in use, suppress showing the speed of progress.

BUGS

       Please report bugs to the ReiserFS developers <reiserfs-dev@namesys.com>, providing as much information as possible--your hardware, kernel,
       patches, settings, all printed messages; check the syslog file for any related information.
