The account was suspended due to inactivity and was later deleted. I understand that your system states that deleted accounts cannot normally be recovered.
However, this website contains important work and unfortunately I do not have a separate backup of the files or database.
I would kindly request you to please check once whether there is any possibility of recovering the account, files, database, or even a partial backup.
I understand that recovery may not be possible, but I would really appreciate it if you could verify whether anything can still be recovered from your side.
Deletions are permanent — neither the account nor its contents can be recovered in any way.
And that distinction is important, because it definitively answers your question.
It doesn’t say “normally” because “normally” suggests that there are exceptional circumstances where recovery is possible. There aren’t. It does say “in any way”, to really confirm that it is impossible.
If your data is important, you should always have a second copy of it somewhere. Anything could happen that could result in you losing access to any data stored anywhere. Never trust a single provider or storage device to keep your data safe.
