|

# Description - egrdbackup performs one task:
|
||||
#
|
||||
# Performs incremental backups of designated directory
|
||||
# hierarchy or backup set (minus any exclusions) into a designated
|
||||
# backup directory.
|
||||
#
|
||||
# The current view of the data at any time will reflect the most
|
||||
# recent state of all the files in the backup set. Diffs for
|
||||
# older versions of all files are stored in hidden directories.
|
||||
# Older versions of any file can be recovered using rdiff-backup directly.
|
||||
#
|
||||
# For example, to recover a backup of the directory (and contents) of
|
||||
# /home/operations from 4 days ago, where the backup directory is /backups, run:
|
||||
#
|
||||
# rdiff-backup -r 4D /backups/home/operations/ /home/operations/recovered-$(date "+%Y-%m-%d")
