Please help !... Using local bib of another user

Is is possible to use the "my lib" of a user and logging with another user, without using sync ?
I did a big mistake, suppressing items and collections from the web site, and with sync, these deleted elements are now also deleted from all my computers. Fortunately, I have a bakcup of my data on disk. But when I restore them, Zotero suppress the deleted items on my local data again...
I thought I could correct this problem by creating a new user on my local database. But when I connect to synch, Zotero suppress all my old data of my first user. How can I solve my problem ?
Perhaps it exists another solution ?
Please... help me... a lot of days of work are on the balance !
