![]() This tool support mounting/compression/network/etc. ![]() bdsync/ bdsync-manager is an amazing tool that can do image backup (full/incremental) by fast block device syncing This can be used along with luks directly on the encrypted partition, incremental backups works very well in this case as well.mount-location-2īackup the original luks disk/partition ( sda or sda1) encrypted as it is to any location crypt_sda1/crypt_sda2 virtual (mapped) un-encrypted partitions sda.Encrypted or classic backup source (luks, dm-crypt/dmcrypt, ext3/ext4/btrfs).Can be scheduled automatically (with cron or else).Full system backup, restorable in one shot.Mount/access the backup disk/files easily.Initial situation as an example (requirement/limitation) Files based backup tools can be: rsync/ grsync, rsnapshot, cronopete, dump/ restore, timeshift, deja-dup, systemback, freefilesync, realtimesync, luckybackup, vembu. This is just an additional protection layer because btrfs snapshot are not true backups! (classic snapshots reside on the same partition).Īs a side note, in addition to disk image backup we may want to do a simple file sync backup for some particular locations, to achieve this, tools like rsync/ grsync (or btrfs-send in case of btrfs) can be used in combinaison with cron (if required) and an encrypted backup destination (like luks-partition/vault/truecrypt). Tools like clonezilla, fsarchiver are not suitable for this question because they are missing one or multiple requested features.Īs a reminder, luks encrypted partition are not dependent on the used file system (ext3/ext4/etc.) keep in mind that the performance are not the same depending on the chosen file system ( details), also note that btrfs ( video-1, video-2) may be a very good option because of its snapshot feature and data structure. With files based backup disk/partition structure is not saved Most of the time for a full restore, the process is a huge time consumer in fact many time consuming steps (like system reinstall) are required and finally backing up installed applications can be tricky Image disk backup avoid all these cons and restore process is a one shot step. When targeting a true full system backup, disk image backup (as required for this investigation) offer substantial advantage (detailed bellow) compared to files based backup. ![]()
