Description:
File system synchronization tool (1-way, over SSH)
fssync is a 1-way file-synchronization tool that tracks inodes and maintains a local database of files that are on the remote side, making it able to: - handle efficiently a huge number of dirs/files - detect renames/moves and hard-links . It aims at minimizing network traffic and synchronizing every detail of a file system: - all types of inode: file, dir, block/character/fifo, socket, symlink - preserve hard links - modification time, ownership/permission/ACL, extended attributes - sparse files . Other features: - it can be configured to exclude files from synchronization - fssync can be interrupted and resumed at any time, making it tolerant to random failures (e.g. network error) - algorithm to synchronize file content is designed to handle big files like VM images efficiently, by updating fixed-size modified blocks in-place . Main usage of fssync is to prevent data loss in case of hardware failure, where RAID1 is not possible (e.g. in laptops). . On Btrfs file systems, fssync is an useful alternative to `btrfs send` (and `receive`) commands, thanks to filtering capabilities. This can be combined with Btrfs snapshotting at destination side for a full backup solution.
