The restore script copies
files back to their original locations. The backup process creates
a folder that is named with the date and time of the backup, as indicated
in the above example. This folder can contain one or more subfolders,
each corresponding to a folder containing GemFire persistence files.
Each such folder contains a restore script called restore.sh or restore.bat
(for example,gemfireBackupFilesDirectory/<date>/<ServerName>_v31_13729_16281/restore.bat /).
Note: For a cluster, the GemFire
persistence folders can be on different nodes. This has the following
implications:
-
In order to restore, the restore
script must have access to the backup folders as well as the GemFire
persistence folders. Therefore, it is recommended that you create
the backup in a shared folder that is accessible from every node in
the cluster. Then, run the script on the nodes that contain the GemFire
persistence folder.
-
You might need to modify the restore
script since the paths to the GemFire persistence folder can be different
on different nodes of the cluster. Because the restore script copies
files from the backup folder to the GemFire persistence folder, it
can be easily modified to correct the path. You can also copy the
files directly, without using the restore script.
Here are best practices
for running the restore script:
-
Restore your disk stores when your
members are offline, and the system is down.
-
Read the restore scripts to see
where they place the files. Make sure that the destination locations
are ready. The restore scripts do not copy over files with the same
names. Therefore, delete all files prefixed with BACKUPmasgemfire
in the SASServer13_n/logs folder,
after they have stopped any SASServer13 processes, before running
the restore script (for example, /gemfireBackupFilesDirectory/<date>/<ServerName>_v31_13729_16281/restore.sh).
-
Run the restore scripts. Run each
script on the host where the backup originated, as shown in the step
above.
The restore process
copies disk store files for all stores containing persistent region
data back to their original location.
