Overhead created by true image with move detection

HI,

We are considering implementing synthetic backups on a Red Had machine with a 5TB GPFS mount point containing millions of small files. As the backups are quite large, "normal" Full backups will cause the machine to consume of 95% of memory and the bpkar process is killed.

I am wondering what sort of overhead True Image restore with move detection will be used on backups in terms of space used, compute and memory on the host.

bpbkar is also being used for synthetics backups. My recommendation is investigating why bpbkar get killed, consider to open a support ticket with Veritas.

"Collect True Image Restore Information With Move Detection" is mandatory when using synthecics backups

Be aware that at least 2 full backups must reside on disk before being moved to tape. Else generation of new full backup might be reading data off tape.
