Features

[edit]
This sectionis inlist format but may read better asprose. You can help byconverting this section, if appropriate.Editing help is available.(January 2019)
  • Support for slices, archives split over multiple files of a particular size
  • Option of deleting files from the system which are removed in the archive
  • Full backup
  • Differential backup
  • Incremental backup,
  • Decremental backup
  • Takes care of any type ofinode (directory, plain files,symlinks,special devices,named pipes,sockets,doors, ...)
  • Takes care ofhard-linked inodes (hard-linked plain files,char devices,block devices, hard-linked symlinks)
  • Takes care ofsparse files
  • Takes care of Linux fileExtended Attributes,
  • Takes care of Linux fileACL
  • Takes care of Mac OS Xfile forks
  • Takes care of some filesystem specific attributes like Birthdate ofHFS+ filesystem and immutable,data-journaling,secure-deletion,no-tail-merging, undeletable, noatime attributes of ext2/3/4 filesystem.
  • Per-file compression withgzip,bzip2,lzo,xz orlzma (as opposed to compressing the whole archive). An individual can choose not to compress already compressed files based on their filename suffix.
  • Fast-extracting of files from anywhere in the archive
  • Fast listing of archive contents through saving the catalogue of files in the archive
  • OptionalBlowfish,Twofish,AES,Serpent,Camellia encryption
  • Optional public key encryption and signature (OpenPGP)
  • Live filesystem backup: detects when a file has been modified while it was read for backup and can retry saving it up to a given maximum number of retries
  • Hash file (MD5,SHA1 orSHA-512) generated on-fly for each slice, the resulting file is compatible withmd5sum orsha1sum, to be able to quickly check each slice's integrity
  • Filesystem independent: it may be used to restore a system to a partition of a different size and/or to a partition with a different filesystem[5]
