Sparse File handling on Linux:
The Disk Agent handles sparse files as one big file, resulting in a log, big backup job that blocks the bandwidth of the backup network unnecessarily. We found a workaround where we identify the sparse files, “unsparse” them using tar and exclude the sparsed files from the backup. This includes manual steps during backup and restore so this is a workaround at best.
found an older change request for the same:
QCCR2A41710 Sparse file backup on UNIX and Linux is not handled in an efficient manner
current state : planned
Please enhance this in a new release or patch
