storeBackupRecover.pl

Restores the backup tree or parts of the backup tree.

       storeBackupRecover.pl -r restore [-b root] -t targetDir [--flat]
              [-o] [--tmpdir] [--noHardLinks] [-p number] [-v] [-n]
              [--cpIsGnu] [--noGnuCp] [-s]

To restore one file or a small number of files, the easiest way is to use cp or a file system browser. This tool is intended to restore (and if necessary uncompress) files. It recreates the backed up data in the same way it was in the original source directory: permissions are set (even if option ignorePerms was set in storeBackup.pl; this option affects only the permissions in the backup tree) and also existing hard links which were in the source tree are reconstructed.

You have to use at least two options: restoreTree and targetDir. StoreBackupRecover.pl only supports command line arguments.

--restoreTree / -r

Backup tree or part of a backup tree to restore. The easiest way to restore something is to go into the backup directory where the tree you want to restore is located. I now assume its name is mydir. Then type:
# storeBackupRecover.pl -r mydir -t /tmp/myRestorePlace
where /tmp/myRestorePlace is the place where you want that directory and all of its content to be restored (see option targetDir).

--backupRoot / -b

Normally, there should be no need to use this option! When you restore a directory, storeBackupRecover.pl does this by searching for .md5CheckSum.info which is in the root directory of each backup. If it finds more than one of these files it generates an ERROR message. This normally will happen if you make a storeBackup backup of a storeBackup backup and want to restore.
If you get an error message like ``found info file a second time ...'', you need to specify the root of this backup (where you recover with the option restoreTree).

--targetDir / -t

The directory where you want the recovered files to be stored. Unless you use option flat, storeBackup always restores the complete backup path to the tree you specified with option restoreTree.

--flat

The directory structure is not restored. All files are stored directly in ``targetDir''. This is only useful if you recover a small number of files.

--overwrite / -o

Overwrite existing files (normally not a good idea). It is better to restore in a separate directory and move files around later.

--tmpdir / -T /tmpdir

Directory for temporary files, default is picked from environment variable $TMPDIR. If it does not exist, /tmp is set as the default value.

--noHardLinks

Do not reconstruct hard links in the restore tree, always copy files.

--noRestoreParallel / -p

Maximal number or parallel started processes to uncompress the files in the backup. Default is 12.
Reduce this number if you are restoring blocked files and the system has insufficient RAM.

--verbose / -v

Print verbose messages.

--noRestored / -n

At the end of restoring, print the number of restored dirs, hard links, symbolic links, files, etc.

--noGnuCp

If you configured storeBackup.pl to use gnucp (option cpIsGnu), so it can backup special files like character devices, then storeBackupRecover.pl reads this information in the backup. But if the computer where you restore the backup has no gnucp installed, you can configure storeBackupRecover.pl not to use cp.
If you made your backup without gnucp, storeBackcupRecover.pl will not use its functionality. There would be no need to do so, because no special files could be backed up.
If you are using GNU/Linux based systems only, it is the best to forget this option.

--createSparseFiles / -s

Creates sparse files from files backuped as blocked files if full blocks are filled with zeros.
