Description
A plea...
Deanna and I have been running this site since 2008 and lately we're seeing a big increase in
users (and cost) but a decline in percentage of users who donate. Our ad-free and junkware-free
download site only works if everyone chips in to offset the revenue that ads on other sites bring
in. Please donate at the bottom of the page. Every little bit helps. Thank you so much.
Sincerely,
your Older Geeks: Randy and Deanna

DAR (Disk ARchive) v2.7.18

A command-line backup and archiving tool that uses selective compression (not compressing already compressed files), strong encryption, may split an archive in different files of given size and provides on-fly hashing, supports differential backup with or without binary delta, ftp and sftp protocols to remote cloud storage.


Archive internal's catalog, allows very quick restoration even a single file from a huge, eventually sliced, compressed, encrypted archive eventually located on a remote cloud storage, by only reading/fetching the necessary data to perform the operation.




Dar saves *all* UNIX inode types, takes care of hard links, sparse files as well as Extended Attributes (MacOS X file forks, Linux ACL, SELinux tags, user attributes) and some Filesystem Specific Attributes (Linux ext2/3/4, Mac OS X HFS+)

Features
• Archiving/backup
• Integrated compression (gzip, bzip2, lzo, xz/lzma) and encryption
• Public key encryption (PGP) and strong encryption (AES, twofish, blowfish, serpent, camellia)
• Sliced archive in files of requested size
• Arbitrarily large file backup and archive creation
• Full/incremental/differential/decremental backup
• binary delta available when performing incremental/differential backups
• Handle any type of inode (directory, plain files, special devices, symlinks, named pipes, sockets, doors...)
• Hardlink support for plain files, special devies, softlinks, named pipes,
• Sparse file detection and restoration
• Extended Attributes support (including Linux ACL and MacOS X File Forks)
• Fast restoration of files even from compressed and/or encrypted archive
• native sftp and ftp protocols support to use remote cloud storage
• Support for tape (sequential reading mode)
• Table contents isolation for use as differential backup or if archive corruption occurred
• On-fly md5, sha1 or sha512 hash file generation for each archive slice
• Hooks for user's scripts between slices
• Hooks for action before and after saving user defined directory of file (suitable for live database backup)
• Detection of file change during backup, possibility to retry a failed file up to a given number times
• Archive merging with default or fine tunable overwriting policy
• Dry-run execution mode
• User comments in archive header
• Archive reslicing without decompression or decryption
• Filesystem Specific Attributes supports (ext2/3/4, HFS+)
• Backup/restoration over ssh or netcat
• Integrated archive protection and repair using Parchive
• truncated archive repairing feature (due to lack of disk space, system crash, power outage)

Changes
v2.7.18
- fixed bug that broke the ability to repair an archive through ftp/sftp
(repairing stays possible locally on the machine where resides the backup)
- fixed the reading of archive header (in-place field) when the -R path
given at creation time was valid or common unix path (/some//path for
example).
- fixed bug met when reading compressed data with multiple threads (-G
option with argument 2 or larger) in sequential read mode.
- fixed bug avoiding dar to repair archives relying on block compression,
testing the "repaired" archive lead to reporting corrupted data for all
compressed files and compressed EA.
- disabling min-digits checks for auxiliary and reference backups when
they are stored in a remote repository (these checks was avoiding using
remote auxiliary and reference backups).
- fixing bug in libcurl adaptation layer to libdar (fichier_libcurl) where
while reading, the end of file was not detected properly in very rare
context, leading the encryption layer trying (and failing) to decipher
the clear data located at end of archive.
- fixed bug met when reading a ciphered backup in sequential read mode with
the help of an external catalog (the few first data and EA were reported
as corrupted in sequential read mode, not in direct read mode or without
the help of an external catalog).
- fixing bug in non-regression test routines, which, once fixed, revealed
the following bugs (about sequential reading mode):
- reading a encrypted and sliced archive in sequential-read mode lead dar
asking for the an after-last non existing slice at the end of the
operation.
- comparing an archive having binary delta patch for a file failed in
sequential read mode with self reporting bug in cat_file.cpp line 1479
- fixing multi-threaded deciphering when reaching the end of the archive
and if a skip() instruction is given from the master thread to change
reading position (bug type message at parallel_tronconneuse.cpp line 662
was reported).
- fixing bug in archive class implementation met when comparing an archive
with filesystem in sequential read mode with the help of an isolated
catalogue. In such context, the hard linked inode can only be compared
at the first hard link encountered, other occurrence are skipped. The
isolated catalog gave a wrong information as it was read in direct mode
while fetching the data and EA to compare were read in sequential mode
without the ability to skip back to re-read a hard linked inode, this
caused the second time comparison to be reported as failed instead of
being flagged as skipped.
- fixing bug met when restoring gpg signed archive in sequential read
mode, where dar/libdar reported failed restoring EA and/or FSA for some
directories.
- fixing bug met when reading archive summary (-l and -q options) in
sequential read mode on sliced archive (was asking for the last slice
due to skip at end of archive while in sequential read mode)
