EOSCMS data deletion prevention measures

"Recycle Bin"

The "Recycle Bin" option is available only in the 0.3.x release of EOS (Beryll). This release will be installed on EOSCMS on 12.11.2013.


- The option can be set per directory. Should be done by administrator.

- Each user can recover deleted files which are owned by him/her.

- The quota for the "Recycle Bin" is one and it is common for the whole EOSCMS.

- Purging of the "Recycle Bin" is done automatically after certain "lifetime" (in ATLAS case for the moment - three days) or manually by administrator. Lifetime is set per file.

- Once the "Recycle Bin" is filled, no more deletes are possible. An alarm on such cases is forseen. For the moment the monitoring is manual.


- All files deleted within the "lifetime" are recoverable.


- Requires additional disk space which is not going to be provided by IT.

- Filling up of "Recycle Bin" prevents file deletion for everybody. This can be prevented by setting proper quota size and coordinating official data deletion compains with the EOS team.

- It does not prevent malicious user from deleting all files with wrongly set linux access
