Understanding storage

Structure of an inSync storage

An inSync storage consists of the following components:

  • Data folder: This component contains the deduplicated data that is backed up from user devices.
  • Database folder: This component contains metadata information about the data deduplication implemented by inSync.
  • Database log folder: This component contains transaction logs for any transaction happening in the database folder.

Guidelines for creating a storage

When creating a storage, follow the guidelines specified in the table below.

Folder Guideline
Data folder
  • It can be created on a local drive, Storage Area Network (SAN), or a Network-Attached Storage (NAS).
  • It is recommended that the folder is created on a separate disk.
  • Use RAID 5.
  • Block the folders from Antivirus scan.
Note: For a backup to be successful, there must be at least 10 GB of free space on the storage data folder. inSync checks for this condition every 10 minutes and if it is not satisfied, ongoing backups are stopped and scheduled backups are put on hold. Backups do not start until you increase the free space to at least 50 GB.
Database folder
  • It must be created on a local drive. Do not create this folder on a networked or shared drive.
  • It must be created on a separate disk.
  • The disk must have at least 4 GB of free space at all times.
  • If you expect more than 1000 users to backup their data on the storage, create the database folder on a Solid State Drive (SSD).
  • Use RAID 10 or RAID 1. Do not use RAID 4, RAID 5, or RAID 6.
  • Block the folder from Antivirus scan.
Database log folder
  • It must be created on a local drive. Do not create this folder on a networked or shared drive.
  • It is recommended that the folder is created on a separate disk.
  • The disk must have at least 4 GB of free space at all times.
  • Use RAID 1.
  • Block the folder from Antivirus scan.
