Recover Data

Similar to the archive process, recovering archived folders is a complex process. Some of the key factors that impact recovery times are:
Number of objects
Path depth
The total size of the dataset to be recovered
Following are the steps to recover data using Hibernate service:
Step 1: Within Starfish GUI, change the mode (top left) to 'Recovery' mode. By default, the mode is set to "Browsing (Latest data)'.
Step 2 (Identify the data): In 'Recovery' mode, users will be able to see previously archived data. Navigate to the directory you wish to recover.
Step 3a (Tag the data): Right-click on the particular directory and select Tags > Action Tags > A Hibernate: Recover. If you are unable to tag the folder, please note down the path.
Please do not select the 'Recover' option.
Step 3b: Once you select that, the A Hibernate: Recover tag should appear on the directory
Step 3c: Repeat the procedure to tag all relevant folders and files to be recovered.
Step 4 (Recover data): Once tagging is complete, please complete the Hibernate Service Request form and select the appropriate action tag. This will automatically submit a ticket to the storage team to start the appropriate process.
Factors that affect the archive process also affect the restore process like directory/file sizes, the number of files in a single directory, etc. play a critical role in determining how efficiently data can be archived. Here are some best practices to facilitate an efficient archive process:
Always tag folders and not individual files (except compressed folders - see next tip). If a single file(s) needs to be archived, move it to a folder.
Folders that are small in size but contain thousands of files should be compressed (zip, tar). For example, archiving a folder of size 10GB containing 500,000 files will be treated as 500,001 objects (files+folder) to archive and the same for retrieval. However, if the same folder is compressed, it is treated as one (1) object to archive.
