| special features |
Accurate mode backups are needed to process files deleted since the last incremental | expiration times of backups are determined at creation using a cron-like syntax | can access remote files via everything but SMB; even Ubuntu One or IMAP! |
partial backups (can resume); web interface |
MySQL and Subversion backups, cool logo | Package delta mode (rpm, freebsd) |
dir names include H:M:S |
handles dpkg selections; custom drivers in config file; device mounting/locking |
backup large files as chunks; modification test uses MD5; can check backup MD5sums | incrementals based on mtime (default) or ctime; manual splitting of full backups | RAID emulation; transmits changes when they happen, or runs from cron | supports decoupled rotation; du and diff features; LVM snapshots in v1.3.1+ * plain rsync supports username |
