Moving chunk index on its own will have little effect you really need to move chunk index and add stage volume to have an effect and even then I could not be sure to what extent it will speed up the restore.

Here is the information I have regarding moving the Chunk Index. Please note that this is not a recommended procedure and we would usually carry this out on a webex with the customer but in this instance, its not possible.

With SmartDisk still running.

1) Use 'smartdisk config -show' to establish the current location of the Chunk Index.

2) Use 'smartdisk config --add --volume' to add a new volume to hold the index, favour the volume for "Chunk Index" and deny all others.

3) Use 'smartdisk config --update --volume' to deny "Chunk Index" where it was originally enabled.

4) Shutdown SmartDisk.

5) Edit the file $IDP_ROOT\dedupe\var\usage.file; There will be an entry like this;

[Volume:\\?\C:\SDdata\store]

Index = TRUE

Storage = TRUE

Duplicate this entry so you have it twice. On the original copy edit 'Index = TRUE' to 'Index = FALSE'. On the new entry, edit the volume to point to the new path of the volume added in step 2, change Storage to FALSE.

6) Locate the 'cabindex' directory in the old volume, this will be in the directory pointed to originally by usage.file within the dedupe directory, so for the above, it would be cabindex located in C:\SDdata\store\dedupe.

7) Move the 'cabindex' directory to the path of the new volume with the dedupe\ directory included (See example).

8) Grant the smartdisk non-priv user full control of the new volume, or chmod the directory for linux.

Ensure that the cabindex directory is actually moved and not copied.

Additional Information

Example

-------

smartdisk config --add --volume E:\Index --deny staging --deny storage --deny "disk index" --favour "chunk index"

smartdisk config --update --volume C:\SDdata\store --deny "Chunk Index"

smartdisk stop

edit C:\SD\dedupe\var\usage.file

-------------------

before -

[Volume:\\?\C:\SDdata\store]

Index = TRUE

Storage = TRUE

-------------------

after -

[Volume:\\?\C:\SDdata\store]

Index = FALSE

Storage = TRUE

[Volume:\\?\E:\Index]

Index = TRUE

Storage = FALSE

-------------------

Move cabindex folder from C:\SDdata\store\dedupe\ to E:\Index\dedupe\ Grant full control of E:\Index to smartdisk user.

smartdisk start
