|Online file retrieval|
We have an online backup system from which you can recover earlier versions of any files you may have lost or corrupted.
cd /vol/recover/homes/usernameThe full copy of your home directory as of the previous night is in the sub-directory
full. Each of the
inc-NNsub-directories contain files that changed about NN nights ago.
full/ - last night's copy of your home directory inc-00/ - files that changed between last night and 2 nights ago inc-01/ - files that changed between 2 nights ago and 3 nights ago inc-02/ - files that changed between 3 nights ago and 4 nights ago ...etc. inc-12/ - files that changed between 13 nights ago and 14 nights agoGroup project directories are also backed up and can be found in:
Remember if you copy any files from the backups to your current home directory you need to rename them to avoid overwriting existing files!
In the specific case of your
cp /vol/recover/homes/USERNAME/full/.email ~/IMAP/RecoveredInbox
Now you can use your favourite email client (perhaps after refreshing it's idea of what IMAP folders exist), to select the RecoveredInbox folder, view the messages, and decide which messages to move back into your main Inbox. We recommend that you end up deleting the RecoveredInbox folder - it's only a transitional folder, don't keep it hanging around for ever!
Start -> Run... \\fs-vol.doc.ic.ac.uk\homebackupor
Start -> Run... \\fs-vol.doc.ic.ac.uk\volbackupThe folder "homebackup" will contain backups for your home directory. The folder "volbackup" will contain backups of the /vol areas such as the group project areas. Version details the same as mentioned above for Linux.
inc-12- is deleted, and all the
inc-NNdirectories are renamed as the next one on, forming a shift register -
inc-11is renamed as
inc-11and so on right back to
inc-01. A new empty
inc-00directory is created.
Then, foreach changed file, the previous copy is moved from
(directories are created as needed),
and the new copy is then copied from your home directory into
In fact, we have two identical services, the original system located in Huxley, and to provide greater data resilience should a disaster occur in the Huxley computer room, one located in the College (ICT) machine room on the other side of campus.
The service based in Huxley may be accessed directly by changing
/vol/recover1/ in the above
\\fs-vol.doc.ic.ac.uk\volbackup1 for Windows users.
The service based in the ICT machine room may be accessed
directly by changing
/vol/recover2/ in the above
\\fs-vol.doc.ic.ac.uk\volbackup2 for Windows users.
\\fs-vol.doc.ic.ac.uk\volbackup will point to whichever
of the services we are recommending, and may change from day to day.
