<p></p> <p><b>New page</b></p><div>If a file that you are trying to restore is older than 4 days (e.g. it was overwritten 5 days ago, or maybe deleted 7 days ago) then you will not be able to restore the file from snapshots but it might be in the backup. <br /> <br /> Math/PACM file server is backed up to the University TSM backup servers once a day. Unlike snapshots the TSM backup server will hold a copy of a deleted file for up to approximately 3 months and will also hold up to 3 revisions of a file for 3 months. This backup is not user accessible but we can easily try to retrieve files for you.<br /> <br /> If you need to restore a file that is not anymore in snapshots contact us at [mailto:compudoc@princeton.edu compudoc@princeton.edu] for help. Please include all the relevant information and try to be as specific as circumstances allow. Include:<br /> # the file name<br /> # the directory where the file was/is located<br /> # approximately time of deletion or change <br /> # any other information that might help us locate the file and the precise version that you are looking for<br /> We will attempt the recovery and then inform you if we have been able to retrieve your file(s).</div>
