I have another solution in my mind: a-formating my backup storage with file system (btrfs/ext4/whatever) and mounting it as backup destination b-making a sparse file in it with truncate(1) c-formating sparse file with btrfs to be used as "archive file system" (with compression, checksumming, trim enabled) d-mounting sparse file and rsync my data to it (rsync will preserve ACLs/xattrs) then unmount "archive file system" e-unmount underlying file system of backup storage destination I tested it out and it works In the case you modified the "archive file system" and you want to trim it and re-punch holes in it you can: a-mount it, fstrim it, unmount it b-dd if=sparse_file of=new_sparse_file conv=sparse c-mount it, fstrim it again(not sure why, but it my test it is needed!?), unmount it do this method is safe? do it has any draw backs? again, Any advice would be most welcome Thanks On Wed, Dec 3, 2014 at 12:47 AM, Patrick O'Callaghan <pocallaghan@xxxxxxxxx> wrote: > On Tue, 2014-12-02 at 18:24 +0100, Heinz Diehl wrote: >> On 02.12.2014, Ali AlipourR wrote: >> >> > I need some advice on Backup solutions, what is your personal methods >> > and solutions? >> >> rsync -avxHSAX /source/ /target >> >> You can even use it to move a complete installation to another disk, >> just exchange source with target.
