Slow Validation

Thread needs solution

Backup disk partition on synology DS415+ via lan gigabit, take speed 80MB/s , while validation only 5MB/s.

Why validation process is too slow ?

If copy a file from synology to local pc, speed is 80MB/s.

Hello Fabio,

Thank you for your posting! Could you please provide more details on your settings:

  • what product edition and build version you are using?
  • type of vault (centralized managed or unmanaged)
  • are you validating the whole archive or every backup after creation?
  • is the manual validation just as slow as the scheduled task?

Thank you in advance!

The synolgy ds415+ have 4 disk configured in raid 5.
The disk are Seagate Barracuda 7200rpm 3 TB model ST3000DM001-1ER166.
Two lan 1 Gigabit are configured in Adaptive Load Balancing.

The version of acronis is Acronis Backup 11.7 (build 11.7.44411)
Vault is unmanaged. The backup is scheduled.
The backup at the 12.00 is differential and at the 18.00 is full, validate is enabled for both plan. Backup at the disk level, all partitions and mbr. Compression normal. Validation is enabled after all complete backup and differential, always. I select validate the last backup.

PC mount  windows 7 64 bit, 1 disk Seagate Barracuda 7200rpm 3 TB model ST3000DM001-1ER166, 8 GB di memory, Core I7.

After reboot pc, the speed seems stabilized.

The backup speed varies between 35MB/s and 80MB/s.
The validation speed at 35MB/s and 50MB/s. The validation is long long process and seems to be slow respect backup.

Along the time, the speed of acronis backup is getting lower. Why ? OK , is complex program, but…I wish it was a bit faster, especially in the validation.
