Compression lost when copying .tibx file

Thread needs solution

So here's the problem - We create a backup (.tibx file) with normal compression.  After this is complete, we want to robocopy this offsite as part of our backup strategy.  Here's where the problem kicks in - We have a mirror script for robocopy in place, and when this executes, all of the compression is removed.  Our 1.25TB of backups balloons up to 4.10TB.  Any thoughts on how I can copy these backups and keep the compression in place?  I don't have to use robocopy if another solution is available that will keep the compression.

Hi Troy,

Have you tried using native backup replication functionality available in Acronis Backup 12.5? There are 2 ways: 1) configure 2nd destination within the same backup plan, which will efffectively replicate backups from 1st location into 2nd one in optimal (compressed) manner 2) (if you have Advanced license) configure separate backup replication plan from Plans->Backup Replication , where you can define separate schedule and retention rules used during replication.

P.S. if you still plan to use robocopy as part of your replication strategy then you can try switching to legacy archive format which is more applicable to such manual manipulations with archive files: create a new backup plan -> Backup Options->Backup format->set to version 11.

Thank you.

Hi Vasily, Why the compression will be removed with robocopy to different location? will this also happen if I move the file in any way? I also enabled encryption. Will I have any problem by moving/copying the backup file (tibx) around without using acronis management console?

.tibx format utilizes Sparse File technology available in NTFS file system.  Quick googling reveals that not many tools support it  properly when copying files ( https://superuser.com/questions/657780/copymove-sparse-files-on-ntfs-wi… ), and not just replace sparse regions with zeroes. Try to use the utility mentioned in the thread by this link.
