python - How can I backup and restore MongoDB by using pymongo? -

does pymongo provide api enable backup or export of collections , rows?

let me answer question in 2 parts

• does pymongo provide api enable backup or export of collections , rows?

as of now, no. not provide binding method backup/mongodump

• can 1 use pymongo enable backup or export of collections , rows?

yes. lets assume have collection col following documents in it

{    'price':25,    'name':'pen' }, {    'price':20,    'name':'pencil' }, {    'price':10,    'name':'paper' }, {    'price':25000,    'name':'gold' } 

our aim backup documents satisfy condition price less 100. using pymongo's find function. can done by

db.col.find({'price':{'$lt': 100}}) 

the above code returns cursor object. documents need backup in cursor object.

a simple way insert documents recursively call documents 1 one , insert them.

but far better method use list() on cursor , insert documents in 1 go.

cursor = db.col.find({'price':{'$lt': 100}}) db.backup.insert(list(cursor)) 

the backup collection's content be

{    'price':25,    'name':'pen' }, {    'price':20,    'name':'pencil' }, {    'price':10,    'name':'paper' } 

if there no requirement limit entries backup. 1 can use empty find()

cursor = db.col.find() db.backup.insert(list(cursor))
