Regular scheduled maintenance
Regular, scheduled maintenence is performed on Computerome every first Tuesday of every month.
This maintenance is done on the running system and should be unnoticeable to users; however, occasionately some users may notice a slight performance drop during an update.
Recovery, backup and archiving
Self-service recovery using snapshots
Computerome provides a self-service snapshot recovery option, enabling you to retrieve individual files or whole directory structures that you may have accidentally deleted on a network drive, up to one week back.
To use it, you go to the directory that used to contain the missing file, and change to the hidden
.snapshot directory, where you will find a number of timestamped subdirectories:
Now you just need to go to the subdirectory corresponding to when you last had the items in question, and recover them using
Computerome provides weekly incremental backup system with 1-year retention time. However, it does not provide file versioning ,i.e., only the last version of every file is kept.
Users must specify precisely which directory structures, folders and files are to be included in the backup.
To save space (and money) on the high-performance storage system, it is possible to off-line folders that are not currently being used. Off-lining is a process where the folder is moved to a Hierarchical Storage Management (HSM) system, leaving only a text-file with folder metadata.
Off-lining is performed when requested by the user.
Computerome does not provide long-term archiving of data.
For any data that is to be stored longer than the 1-year backup retention period, the user must provide an own archiving solution.
