File are created once and duplicatedcopy are 'hardlink'. Space-efficient since 'hardlink-created file' do not take up space Note: hardlink' cannot be created in cross-device'(different harddisk system) Why VRangesync 'differential+incremental' backup? ----------------- 1. Easy to restore. Just overwrite destination with any of latest 'differential+incremental'backup(fast and simple). 2. No need restore through a series of 'snapshot'[traditional method](as many as 20 or more which traditional incremental does. it waste time) 3. Vrangesync's method is using 'differential'(direct mirror) + 'incremental'(hardlink) to save space it is works exactly like how rsync '--link-dest' works it work very similar to MACOS timemachine ================================================================================ #How it works : 'differential+incremental' backup #----------------------------------- 1) Issue '-idd "y"' to activate 'differential+incremental' backup $ ./vr -i "/home/syncuser/computerwork" -o "/backup" -idd "y" if it is a new 'differential+incremental' it will create "/backup/home_syncuser_computerwork" & 'DD-MM-YYYY_folder' and start sync eg. /backup/home_syncuser_computerwork/16-Mar-2025:22:04:09 2) subsequent new 'differential+incremental' backup $ ./vr -i "/home/syncuser/computerwork" -o "/backup" -idd "y" a) vrangesync find the 'latest_differential+incremental_backup' in '/backup/home_syncuser_computerwork' b) use 'cp -al' to create a hardlink copy of 'latest_differential+incre_backup' eg. '$ cp -al /backup/home_syncuser_computerwork/19-Mar-2025:16:03:35 /backup/home_syncuser_computerwork/20-Mar-2025:16:00:25' c) Vrangesync will start sync result -------- it will create something like the following example: /backup/home_syncuser_computerwork/16-Mar-2025:22:04:09 (oldest backup) /backup/home_syncuser_computerwork/18-Mar-2025:22:04:04 (subsequent diff+incre backup will use 'hardlink' to link to originalfile. it save space.) /backup/home_syncuser_computerwork/19-Mar-2025:16:03:35 ================================================================================ # Howto - restore #----------------------------------- -Every Vrangesync 'differential+incremental' is a COMPLETE backup; you can restore from any of the datedbackup # Restore to new disk 1) select your desired_dated backup from storagebackup and sync it over to your destination $ ./vr -i "/backup/home_syncuser_computerwork/16-Mar-2025:22:04:09" -o "/home/syncuser/computerwork" or $ ./vr -i "/backup/home_syncuser_computerwork/19-Mar-2025:16:03:35" -o "/home/syncuser/computerwork" when you sync these 'differential+incremental' backup for restore, it will convert file(which are 'hardlink' in storagebackup) and create a 'truecopy' on the destination ================================================================================ what happen to the deleted file&dir when you start create new 'diff+incremental'backup? 1. every diff_incre_backup is a COMPLETE backup 2. every vrangesync (idd) will mirror from source to your destination's 'newest_datedbackup' 3. on restore, you just need to select your desired_dated backup from storagebackup and sync it over to your destination it will convert file(which are 'hardlink' in storagebackup) and create a 'truecopy' on the destination Q: why you do not use 'compression' after do differentialbackup which you implement previously? it will take age if you are trying to compress 500gb or more data into a singlefile and especially with 'xz' ############################################### 25 feb 2025 VRangesync (20250225) stable release! https://www.1range1.com/index.php#download New changes(changelog): ----------------------------- - Vrangesync will log activity to $HOME/vr.log by default.
